Solution:
Sexual reproduction, which involves meiosis. In sexual reproduction, two parents each contribute a cell, a gamete, to their offspring. This method produces offspring that differ genetically from each parent, as well as from each other. This genetic variation among offspring means that some of them may be better adapted than others to survive and reproduce in a particular environment. Thus, this genetic diversity provides the raw material for natural selection and evolution.
So that, we can conclude that the correct answer is:
SEXUAL REPRODUCTION.
