A mitosismitosis
B behaviorbehavior
C mutationmutation
D natural selection

Answer 1

The correct response is D natural selection.

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce more than those that are not, leading to evolutionary changes over time. While mutations (C) are a source of genetic variation that can be acted upon by natural selection, the process of adaptation and evolution itself is primarily driven by natural selection.
