Model Answer

Option A is correct. Both A and R are true, and R is the correct explanation of A. Reproduction is not needed for an individual's survival; only nutrition, respiration, and excretion are essential life processes. Reproduction merely increases population size.

Explanation

The textbook explicitly states: "reproduction is not necessary to maintain the life of an individual organism, unlike the essential life processes such as nutrition, respiration, or excretion." The Reason directly and correctly explains why the Assertion is true — it contrasts essential individual life processes with reproduction, which serves the species, not the individual. So Option A is the right choice.
