A teacher who pays more attention to the boys in class or a committee that preferentially awards scholarships to male students is engaging in ________.

A) self-fulfilling prophecy
B) intrusive interruptions
C) sex discrimination
D) heterosexism

Sex discrimination is treating someone unfairly or differently because of their sex. If a teacher pays more attention to boys in class or if a committee gives scholarships preferentially to male students, it is considered discriminatory behavior based on sex. A self-fulfilling prophecy refers to a belief or expectation that causes itself to become true, and intrusive interruptions refer to interrupting or disrupting someone excessively in a conversation. Heterosexism refers to discrimination or prejudice against non-heterosexual people. Therefore, the correct answer is C - sex discrimination.
