If an organism has a favourable variation how can its chance of survival be?

Answer and explanation

Correct answer: It can increase

Natural selection explains why a favourable variation can improve survival. If a variation helps an organism obtain food, avoid predators, tolerate conditions, or reproduce more successfully, that organism may leave more offspring than others. The advantage does not guarantee survival, but it can increase the probability. Thus option A is correct; the other choices are absolute and biologically unsupported.
