Final answer:
Women adding red color to their lips because it indicates fertility aligns with the Evolutionary theory. This theory is about how traits that increase chances of reproduction can become prevalent in a population.
Step-by-step explanation:
The fact that women initially began adding red color to their lips because red indicates fertility and health is best illustrated by the c) Evolutionary theory. This theory is concerned with how evolutionary processes have shaped behaviors related to survival and reproduction. In contrast, social role theory relates to patterns of behavior that are culturally expected of men and women, social learning theory involves learning behaviors through observation and imitation, and biological theory relates to the physiological and genetic mechanisms in the body.
Within the context of evolutionary psychology, traits that enhance the probability of reproduction and survival are often passed down through generations. The preference for red lips can be seen as an adaptation that signals health and therefore enhances the individual's reproductive success. This aligns with the good genes hypothesis, which suggests that certain traits are preferred because they indicate the genetic fitness of a potential mate.
