Frank Works as a Cook at the Breakwater Swim and Tennis

Frank works as a cook at the Breakwater Swim and Tennis Club. He is enamored with Brenda, one of the swimming instructors. She has shown no interest in him but he has been stalking her, and making threats and degrading sexually charged comments to her. Frank has been careful to keep his behavior very low-profile. If Brenda can bring a claim of sexual harassment against Frank, Breakwater:

A) will be liable for Frank's behavior, regardless of the state of its knowledge of her activities.
B) will not be liable for Frank's behavior, unless it can be shown that it knew or should have known of Frank's behavior and took no action.
C) cannot be held liable for Frank's behavior, under any circumstances, since he was not a supervisory employee of Breakwater.
D) will have a cause of action against Frank for intentional infliction of emotional distress.
