C. Natural selection favors individuals that reproduce more than others.
Explanation:
Genetic variations present in the population are acted upon by natural selection. The organisms that have the adaptive traits which in turn make them able to survive and reproduce more than the other individuals are favored by natural selection.
Over generations, natural selection leads to the evolution of a new population with an increased frequency of the gene responsible for the selected adaptive trait.
For example, the bacteria with antibiotic resistance were favored by natural selection as they can survive and produce more progeny in the presence of antibiotics than the bacteria lacking the gene for antibiotic resistance.
