UGC NET Questions (Paper – 1)

Statements A, B, C, D and F are correct: solid fuels and poor ventilation raise indoor pollutants; exposure increases respiratory risks especially for women/children; cleaner fuels/improved stoves reduce exposure; and additional sources include materials, tobacco and chemicals. Statement E is false because exposure is strongly shaped by time spent indoors and gendered household roles. Hence, the correct combination is A, B, C, D and F only.

Option A:
Option A is correct because it includes all true statements and excludes only E, which wrongly denies the importance of time use and gender roles in exposure.

Option B:
Option B is incorrect because it omits F, thereby ignoring important indoor sources like building materials, tobacco smoke and household chemicals.

Option C:
Option C is incorrect since it includes E (false) and also omits A, missing the key role of solid fuels in indoor smoke generation.

Option D:
Option D is incorrect because it omits B, underplaying the critical role of ventilation in determining indoor concentrations.
