The correct response is:
Changes in the environment can act only on existing variations in a population.
This statement reflects the principle that natural selection operates on the variations that already exist within a population. Changes in the environment can influence which traits are advantageous, but they do not create new variations; rather, they select from the existing variations based on how well-suited they are to the new environmental conditions.
