Explanation:

Genetic drift is a mechanism of evolution that changes allele frequencies in a population due to chance events. Mutations are caused by other factors, and moving organisms is migration, not genetic drift. So the correct option is the one stating it changes allele frequencies.

Answer:

It changes the allele frequencies of a population.
