D

B makes no sense

Organisms within a population must be genetically variable in order for natural selection to occur.

What is Genetic Variability?

It is the existence of different genes within the gene pool of a population.

The existence of different genes within the gene pool will give room for natural selection to either select for or against a particular gene or genes.

Assuming all the individuals in a population have the same genes, a change in environmental factors can lead to the extinction of the entire population.
