Answer:
c. Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits.
Explanation:
Natural selection works on a population when genetic variations are present in its members. Some genetic traits make the organisms better adapted to the prevailing surroundings. These individuals survive more and reproduce more successfully due to the presence of specific genetic traits. Over the generations, the proportion of the beneficial genetic trait increases due to the increased reproductive success of these individuals. This is called natural selection. On the other hand, the individuals that lack these traits survive and reproduce less.
