Natural selection acts on already existing variations. What does this correctly mean?

Answer and explanation

Correct answer: Nature does not instantly create a new trait according to need

The governing concept is natural selection acting on variation already present in a population. Individuals may differ because of inherited genetic variation; if one difference improves survival or reproduction, that variant can become more common over generations. Nature does not produce a trait because an organism suddenly needs it. Therefore option A is correct. Options B and C deny the need for variation, while D confuses acquired characteristics with inherited traits.
