According to Canadian Researchers Taylor and Colleagues, Females Are More

According to Canadian researchers Taylor and colleagues, females are more likely than males to manifest the "tend or befriend" response style rather than the "fight-or-flight" response pattern when faced with extremely stressful events. What is the hypothesized evolutionary explanation for this difference?

A) Since females are not as physically capable as males to defend against aggressors, and since they spend more effort at caring for their offspring, women tend to join social groups in order to reduce their vulnerability to dangerous stressful events and to secure resources
B) Since women live longer than men, they cannot afford to engage in a "flight or fight" response when dealing with a dangerous threat
C) Since females have been denied rights and privileges that males have taken for granted, women have had no choice but to concentrate on establishing complex social networks in order to deal with stressful events
D) Since females have increased levels of estrogen rather than testosterone, they are unable to maintain the fight-or-flight response
