UGC NET Questions (Paper – 1)

Statements A, B and D are correct as they reflect established public health knowledge about contaminated water, vulnerability of children and benefits of integrated WASH programmes. Statement C is incorrect because handwashing with soap at critical times is one of the most effective measures to prevent diarrhoeal and related diseases. Therefore, the combination A, B and D only is the correct answer.

Option A:
Option A is incorrect because it excludes D, which correctly emphasises the value of integrated WASH interventions. Without D, the answer does not show how combined strategies reduce disease burden.

Option B:
Option B is incorrect since it includes C, which wrongly downplays the effectiveness of handwashing. Including this false statement makes the combination unacceptable.

Option C:
Option C is incorrect as it groups B, C and D and accepts C as true. While B and D are correct, C is not, so the option mixes true and false statements.

Option D:
Option D is correct because it recognises that unsafe water and sanitation particularly harm children and that integrated WASH programmes can substantially lower disease. It also correctly rejects statement C.

Statements A, B, D and F are correct as they highlight safe water, sanitation, solid waste management and vulnerability of age groups. Statement C is wrong because handwashing with soap is highly effective in interrupting disease transmission. Statement E is also wrong, since environmental health includes both biological and chemical risks. Therefore, the combination A, B, D and F only is correct.

Option A:
Option A is incorrect because it includes C, which understates the importance of handwashing, and it omits F.

Option B:
Option B is incorrect as it includes E, which wrongly narrows environmental health to chemical issues.

Option C:
Option C is incorrect because it accepts E and omits A, denying safe water’s central role and limiting scope.

Option D:
Option D is correct since it selects A, B, D and F and excludes C and E.

Statements C and F are wrong, while A, B, D and E are correct. Indoor air pollution from solid fuels is a major risk factor for respiratory disease, so saying it has no effect is clearly false. Environmental health programmes routinely include behaviour change components, such as promoting handwashing and safe storage, so claiming they never consider behaviour change is also wrong. The other statements describe widely accepted WASH–health relationships. Hence, the wrong statements together are C and F.

Option A:
Option A is incorrect because it identifies only C as wrong and ignores F, which also misrepresents environmental health practice. It therefore fails to capture the full set of incorrect statements.

Option B:
Option B is incorrect since it treats D as wrong along with C, yet D correctly notes that children are more vulnerable to environmental risks due to physiology and exposure patterns. Misclassifying D undermines basic public health understanding.

Option C:
Option C is correct because it selects exactly those statements that contradict established evidence on indoor air pollution and health promotion strategies. It leaves A, B, D and E recognised as the valid foundations of WASH programming.

Option D:
Option D is incorrect as it adds A to the list of wrong statements even though A accurately describes the link between unsafe water, sanitation and diarrhoeal disease. Grouping A with C and F makes the option logically inconsistent.
