Which of the following statements is most consistent with the evolutionary principles that explain why male sexual promiscuity is regarded as being more acceptable than female sexual promiscuity?

a. Because men release over 200 million sperms per ejaculation and women have only one egg to fertilize, men need to have sex with many different partners to ensure that at least some of his sperm will successfully create a zygote with his genetic code. b. Because men have external genitalia that go through the changes of sexual arousal faster than the internal genitalia of women, their increased sexual activity is seen as being consistent with the plans of nature. c. Men have greater sexual reproductive potential, so impregnating many partners is seen as crucial to the survival of a man's genes. d. Because men are more dominant in society, it makes sense that they should have more sex with more female partners than women. Women's submissive role in society relegates them to a standard of having only one partner, getting pregnant, and then staying with that single partner.
