D is Correct.
Sexual harassment includes unwelcome sexual advances and other behavior that is sexual in nature or is based on sex. In this example, the supervisor’s conduct was sexual in nature because he commented on Suzy’s appearance, promised her a raise if she agreed to go out with him, and touched her inappropriately. There is no indication that Suzy welcomed the supervisor’s conduct; in fact, she reported his conduct to the pool manager in the hope that the manager would put a stop to the harassment.
