In which condition can a mutation contribute to evolution?
Answer and explanation
Correct answer: When it occurs in a reproductive cell and can pass to offspring
A mutation is a change in genetic material, but it can influence evolution only when its effect is heritable. A mutation in a germ cell or an early cell giving rise to gametes may enter the next generation. If it occurs only in a body cell, it usually affects the individual but is not inherited. Thus option B is correct; the other choices describe injury, no mutation, or non-reproductive lethality.
