The correct response is:
Changes in the environment can act only on existing variations in a population.
This statement reflects the idea that natural selection acts on variations (traits) that are already present in a population. Changes in the environment can influence which traits are advantageous and thus affect the fitness of organisms, but they do not create new variations themselves; rather, they select for certain existing variations.
