Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : DDT bioaccumulates in tissues of many species including humans.
Reason (R) : DDT is relatively insoluble in water but readily soluble in fats and oils.
In the light of the above statements, choose the most appropriate answer from the options given below :
- A.
Both (A) and (R) are correct and (R) is the correct explanation of (A)
- B.
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- C.
(A) is correct but (R) is not correct
- D.
(A) is not correct but (R) is correct

Show answer & explanation
Correct answer: A
Assertion (A) is true: DDT bioaccumulates in tissues of many species. Reason (R) is true: DDT is lipophilic and water-insoluble. The fat-solubility prevents excretion via water-based systems, leading to accumulation in fatty tissues. Thus, Reason correctly explains Assertion.
