Answer:
D.) It has genetically diverse members that compete for resources.
Step-by-step explanation:
Natural selection is the process of species evolving over time. For this to occur, there needs to be differential survival and heredity through reproduction. Differential survival refers to the idea that some individuals in a species have a better chance of surviving based on differences in their phenotypes. These genetic differences allow them to somehow have better control/access to resources that promote survival and reproduction. Individuals without this trait will slowly be outcompeted for resources and eventually die off, leading to evolution by natural selection.
