Which statement best explains how natural selection determines differential survival when a population is under resource stress?

A.
Individuals with favorable traits are more likely to survive and reproduce than those with less favorable traits.
B.
Groups of individuals whose traits are very similar are more likely to survive and reproduce than groups whose individuals are genetically diverse.
C.
Groups whose individuals are generalists are more likely to survive and reproduce than groups of individuals who are specialists.
D.
Individuals who possess more common genotypes are more likely to survive and reproduce than those who possess rarer genotypes.

Answer: The correct answer is- A. Individuals with favorable traits are more likely to survive and reproduce than those with less favorable traits.

Natural selection is an evolutionary process according to which individuals that can better adapt to the changing environmental conditions, survive and produce more of their kind through reproduction.

In other words, individuals with beneficial/ favorable traits ( for survival and reproduction) are selected and others are eliminated. In this way, natural selection determines differential survival when a population is under resource stress.

Thus, option A) is the right answer.
