Answer;
A- reproduction
Explanation;
-Reproduction is a biological process through which new individual organisms are produced from their parents. It is a fundamental feature of all living organisms; each individual organism exists as the result of reproduction.
-There are two types of sexual reproduction, namely; sexual and asexual reproduction. Unlike sexual reproduction, which requires genetic material from two parent organisms in order to create an offspring, asexual reproduction occurs when a single organism reproduces without the genetic input of another.
