What can a useful variation do for an organism?
Answer and explanation
Correct answer: It can increase the chance of survival
A useful variation is an inherited difference that improves an organism’s suitability to particular environmental conditions. For example, better camouflage or resistance to a disease may increase the probability of surviving and reproducing. Natural selection can then make such a variation more common in later generations, though usefulness depends on the environment and is not guaranteed. Therefore, option A is correct. B, C, and D describe impossible or harmful effects, not adaptive variation.
