Elaine Has Heard a Disturbing Rumor from Tori, Who Heard

Elaine has heard a disturbing rumor from Tori, who heard it from Chantelle. Supposedly, Colleen, an entry-level administrative worker, was working late when the company president came by her desk and asked her out for a drink. She declined politely and would have let the matter go if he had not proceeded to start massaging her shoulders, at which point she left quickly. As a member of top management, Elaine knows the company president well, and from her experience, he seems to be a happily married man who in any case would never do something so unprofessional and inappropriate. Given her role in the company, Elaine should

A) go straight to the company president, inform him of the story that is going around, and be prepared to take any action he deems appropriate.
B) talk to Colleen first, and if she confirms the story, go to the company president; but if she denies it, then Elaine should talk to each of the people who spread the rumor.
C) arrange a round-table discussion with Tori, Chantelle, and Colleen, so as to find out who said what to whom and where the story originated.
D) do nothing, since she knows the company president to be a church-going family man who could not conceivably do anything so inappropriate.
E) arrange a meeting with the company president to discuss the organizational sexual harassment policy, then use this as an opportunity to talk about the rumor.
