(C) It creates new combinations of genetic variants, increasing the chances that some individuals survive environmental changes.
(D) It allows a single individual to produce many offspring very quickly.

Model Answer
(C) It creates new combinations of genetic variants, increasing the chances that some individuals survive environmental changes.
Explanation
The passage in section 7.1.1 directly states that variation is useful for the survival of species over time — if a niche changes drastically, individuals with variations have a chance to survive. Modes of sexual reproduction allow greater variation to be generated (from "What you have learnt"). Options A and D describe advantages of asexual reproduction; Option B describes asexual reproduction (identical offspring). Always link sexual reproduction → variation → survival in changing environments.
