C) it is necessary for the survival of the individual.
Explanation:
Sexual reproduction is rarely, if ever, necessary for the individual. This is not a reason for its importance. However, while not important for the individual, sexual reproduction is important for the species. It allows genetic variability among offspring, as well as mutations.
