The correct answer is: C.The introduction of new alleles due to migration.

Explanation:

Migration (or gene flow) involves the movement of alleles between populations, which can alter allele frequencies in a population. This introduces new alleles or removes existing ones, causing a deviation from Hardy-Weinberg equilibrium.

The other options would not lead to a deviation from Hardy-Weinberg equilibrium:

A.A large population size and no migration: A large population size helps reduce genetic drift (rando...
