A- Abstaining from any sexual activity
The answer is force because Force is needed to change the direction of a moving mass.
It is D, sharing appreciation for what is being said. Both A and B aren't crucial to being a good listener, in fact in practice they effectively draw attention to yourself, which would be fine if the question was regarding being a good conversationalist. Additionally, C is just completely irrelevant, that wouldn't even be a good conversation practice, let alone a trait important to listening.
Sexual harassment ranging from name calling and inappropriate flirting, all the way to sexual misconduct, can have major negative consequences on both male and female mental health.
Short term, I would say A, low self image and self esteem. A seems to be the best answer.
