Children and environmental exposures – UGC NET Question

Statements A, C and D are correct because toxic exposures in childhood affect development, indoor smoke increases respiratory disease and policy interventions can create healthier environments. Statement B is incorrect; children are actually more, not less, vulnerable due to developing organs and higher exposure per unit body weight. Hence, the combination that includes A, C and D and excludes B is the correct answer.

Option A:
Option A is correct since it recognises all the true statements and leaves out B, which misrepresents children’s vulnerability. It captures both biomedical evidence and the role of preventive policies.

Option B:
Option B is incomplete because it excludes D, which rightly points to the importance of policies targeting homes, schools and neighbourhoods. Without D, the policy dimension is missing.

Option C:
Option C is incorrect as it includes B, which is a false statement about children’s comparative vulnerability. Even though C and D are true, accepting B makes the combination unacceptable.

Option D:
Option D is incorrect because it claims that all four statements are correct, thereby endorsing B along with the others. This contradicts basic environmental health understanding.
