If a trait helps survival but does not pass to offspring, why will its contribution to evolution remain limited?

Answer and explanation

Correct answer: Because evolution requires the trait to pass across generations

The governing concept is heredity in evolution. Evolution involves a change in the frequency of heritable traits in a population over successive generations. A useful trait may help one individual survive, but if it is not inherited, it cannot become more common through reproduction. Therefore, option A is correct. Survival alone is not enough; options B, C, and D incorrectly ignore inheritance or make false generalisations.
