c. migration
d. variation

Respuesta :

Answer:

B.

Explanation:

Evolution is a change in the gene pool of a population over time. It occurs throughout the whole population. The gene pool in this situation changes from consisting of genes for mostly brown-colored insects to green. Mutation only occurs in individuals. Migration refers to population moving locations. Variation is just the different genes in a gene pool.
