b) allow new genes to flow into the population of organisms.

c) must favor reproduction of individuals with certain traits.

d) eliminate individuals from the population at random.

Answer #1

In a population, certain individuals have trait or characters that makes it more suited for the environment. Such individuals are chosen by ntural selection. These organisms have high success rate of reproduction due to their new traits or characters which makes them better suited for environmental conditions. As this reproductive advantage continues, this organisms with this specific traits starts proliferating in the population in next few generations.

So, correct answer is (c) must favor reproduction of individuals with certain traits.
