Answer:
A. Migration
Explanation:
Migration is one of the evolutionary forces that change the allele frequencies of the population. Migration refers to the movement of individuals from one population to another. As the individuals move out of a population, transfer of alleles also takes place. When the immigrated individuals interbreed in a new population, they add new alleles to the gene pool of that population.
In the given example, 200 garter snakes moved out of the population resulting in changed allele frequency of the original population. Since the changed allele frequency was due to the movement of snakes, it represents migration.
