Statement 1: A straight chain alkyl sulphonate is almost biodegradable while branched alkyl sulphonate is non-biodegradable.

Statement 2: The hydrocarbon side chain stops bacteria from attacking and breaking the chains.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
