How would the evolutionary perspective explain the fact that men across cultures rate women with a smaller waist-to-hip ratio as being more attractive?

A) they are more likely to have multiple-birth pregnancies
B) they are more likely to be able to successfully have children
C) their smaller waists accentuate the appearance of the size of their breasts
D) smaller WTH is associated with greater intelligence.

From an evolutionary perspective, men may be attracted to women with a smaller waist-to-hip ratio because it is a reliable indicator of a woman's reproductive potential. A smaller waist-to-hip ratio is associated with higher levels of estrogen and better fertility, which would increase the likelihood of successful reproduction. Therefore, men who are attracted to women with a smaller waist-to-hip ratio may be more likely to successfully reproduce and pass on their genes.
