C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
