If a change is useful but not inherited, why will it not play a lasting role in evolution?

Answer and explanation

Correct answer: Because evolution is linked with inherited changes across generations

Evolution is a population-level change that becomes visible across generations. A useful characteristic can help one individual survive, but it can influence the future of a population only if the genetic basis of that characteristic is transmitted to offspring. Without inheritance, the change usually ends with the individual and cannot accumulate through reproduction. Thus option A is correct. B is false because usefulness does not guarantee inheritance, while C and D contradict basic evolutionary biology.
