D Correct answer
Explanation

Reproduction is essential for the survival of a species but not for the survival of an individual organism. An individual can live without ever reproducing. Digestion, respiration, and excretion are essential life processes that maintain the individual organism's survival. Without these processes, the individual organism would die quickly.
