For Many Years, Saturday Night Live Ran a Series of Skits

For many years, Saturday Night Live ran a series of skits about a character named Pat. The premise of each skit was that no one could tell if Pat was male or female. The other characters would devise ingenious plots to determine Pat's gender, but all attempts failed. The humor in these skits is based on the fact that

A) men have historically had access to most of society's material resources and privileges. Consequently, they generally seek to maintain their dominant status.
B) gender identity is so important to our social selves that we can barely interact with anyone without first determining that person's gender.
C) Pat was trying to avoid being classified as a woman because expressive and instrumental roles may be complementary, but the social rewards for filling them are far from equal.
D) transgender and gender-nonconforming people are challenging old ideas about the relationship between sex and gender.
