UGC NET Questions (Paper – 1)

Statements A, B, C and E are correct because standards exist for air, water and noise, and regular monitoring is required to see whether actual conditions meet these limits. Statement D is false, since even legally binding standards require regulatory institutions, penalties and compliance mechanisms to be effective. Statement F is false too because public disclosure of data supports transparency and can create pressure for better enforcement. Therefore, the set that keeps A, B, C and E while excluding D and F is correct.

Option A:
Option A is incorrect as it omits E and thereby ignores the crucial role of monitoring in making standards meaningful. Without E, there is no way to check compliance systematically.

Option B:
Option B is incorrect since it leaves out C, thus failing to mention noise standards, which are part of environmental quality frameworks, especially in urban areas.

Option C:
Option C is incorrect because it includes D, which wrongly suggests that standards never need enforcement mechanisms. Including D mixes a clearly false claim with correct statements.

Option D:
Option D is correct as it retains all the true statements about what standards are and how they are applied, while rejecting the idea that enforcement and public information do not matter.

Statements A, C and D correctly describe multiple ecosystem services of urban green spaces. Vegetation can reduce heat island effects, enhance air quality, provide habitats and extend greenery through roofs and walls. Statement B is incorrect because urban green spaces are recognised for supporting mental health, recreation and social interaction. Hence the combination that includes A, C and D while excluding B is the correct answer.

Option A:
Option A is incorrect because it includes only A and C and leaves out statement D. While A and C are true, D is also a correct statement about green roofs and walls contributing to urban greening and climate adaptation. Omitting a true statement makes this option incomplete.

Option B:
Option B is incorrect because it treats B as correct along with A and C. Statement B wrongly denies the psychological and recreational benefits of green spaces, which are well documented in urban planning and public health literature. Including this false statement invalidates the option.

Option C:
Option C is correct because it groups exactly the three accurate statements A, C and D and excludes the one false statement B. It reflects a rounded understanding of how urban green infrastructure contributes to cooling, air quality and biodiversity as well as innovative building-level greening.

Option D:
Option D is incorrect because it accepts B, C and D. The presence of B, which incorrectly claims no role of green spaces in mental health and recreation, makes the overall combination wrong even though C and D are true.

Statements A, B, C, D and F are correct: walking/cycling are NMT; infrastructure encourages use; NMT has no tailpipe emissions; it reduces congestion and improves air/health; and integration with public transport improves mobility. Statement E is false because NMT planning is important in cities across all income levels. Therefore, the correct set is A, B, C, D and F only.

Option A:
Option A is incorrect because it omits F, missing the important role of integrating NMT with public transport for a complete mobility system.

Option B:
Option B is correct because it includes all true statements and excludes only E, which wrongly restricts NMT relevance to low-income countries.

Option C:
Option C is incorrect because it includes E (false).

Option D:
Option D is incorrect because it omits B and A, so it underrepresents both infrastructure and the definition/examples of NMT.

Statements A, B and C are correct because they define urban carrying capacity, identify key indicators and show how the concept can inform planning. Statement D is incorrect as it assumes technology can fully remove ecological limits, which is unrealistic. Thus, the combination A, B and C only is the correct answer.

Option A:
Option A is incomplete because it omits C, which correctly links carrying capacity analysis with actual planning decisions on limits and zoning. Without C, the practical application of the concept is not fully reflected.

Option B:
Option B is incorrect as it lists only B and C and leaves out A, which provides the core definition of urban carrying capacity. Without the definition, the answer is conceptually incomplete.

Option C:
Option C is correct because it gathers the three true statements and excludes D, which downplays ecological constraints. It captures both the meaning and use of carrying capacity in urban planning.

Option D:
Option D is incorrect since it treats all four statements as correct, thereby endorsing D’s claim that carrying capacity can be ignored due to technology. This contradicts sustainability principles and invalidates the option.

Urban green planning involves designing and managing vegetation,parks and green corridors to enhance environmental quality and livability in cities. Street tree plantations directly contribute to this goal by improving air quality,providing shade and mitigating noise. The stem describes exactly such activities,so “green” planning is the correct term. Therefore Option D is appropriate.

Option A:
Industrial planning focuses on industrial location and development,not on integrating vegetation for ecosystem services in cities.

Option B:
Transport planning addresses mobility networks; tree planting can support it but the activity described is primarily about greening and ecosystem benefits.

Option C:
Energy planning concerns supply and demand of energy systems,not roadside tree programmes for pollution and shade benefits.

Option D:
Green planning explicitly integrates natural elements to improve air quality,shade and noise reduction,matching the example in the stem.
