How can small inherited changes in organisms produce a large change over a long time?

Answer and explanation

Correct answer: They can accumulate over generations and change the characteristics of a population.

Inheritance allows a variation to pass from parents to offspring. If a small change improves survival or reproductive success, natural selection may make it more common in later generations. Other variations can accumulate with it, and the combined shift in trait frequencies can gradually produce a major difference in the population. Therefore option A is correct. The distractors contradict inheritance or incorrectly treat evolutionary change as immediate or unrelated to populations.
