The offsprings of better-adapted individuals are expected to make up a larger proportion of the next generation. The most likely explanation is:
Correct answer: C. Natural selection
- A. Mutation
- B. Inheritance of Acquired characters
- C. Natural selection
- D. Genetic drift
Explanation
When better adapted individuals survive and reproduce more, their offspring form a growing share of the next generation, which is exactly Darwin's natural selection. Mutation supplies new variation but does not explain why the adapted forms increase, and genetic drift changes frequencies by chance rather than by adaptation.

About Darwinism
Darwinism explains evolution through inherited variation, competition for limited resources, survival and reproduction of better-adapted organisms, and natural selection over generations. It is distinguished from Lamarckism because Darwin's explanation depends on selection acting on existing heritable differences, not the inheritance of acquired characteristics.
