Natural selection acts most effectively on which type of traits?

Answer and explanation

Correct answer: Traits that are heritable and provide a survival advantage.

Natural selection requires variation among individuals, and its evolutionary effect is strongest when the variation is heritable and affects survival or reproduction. Individuals with a favourable inherited trait are more likely to reproduce and pass that trait onward, so its frequency may increase. Option A contains both requirements. Learned-only, non-genetic and identical traits cannot be efficiently selected across generations in the stated sense.
