Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Passive absorption is a physical process, occurring in the direction of concentration gradient, it does not involves any biological process or energy input. Hence, it is non-metabolic in nature and is very fast as compared to active transport, which occurs against concentration gradient and requires input of metabolic energy. Active and passive absorption are two different processes. Characteristics of one cannot be an explanation of another and vice versa.
So, the correct answer is option B.
