Urban green spaces functions – UGC NET Question

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.
