What findings by Buss et al. (1992) does DeSteno and Salovey's (1996) double-shot hypothesis attempt to explain away?

A) Men are attracted to women with a high hip-to-waist ratio, while women are attracted to men with a high shoulder-to-hip ratio
B) Men get more upset when they think about their romantic partner's sexual infidelity, while women react more negatively to thoughts of their partner's emotional infidelity
C) Both men and women are more upset by thoughts of repeated sexual infidelity compared to one-time sexual infidelity; only men, however, are upset by a single instance of emotional infidelity
