Question

which best defines the different forms of sexual harassment?
any forced sexual activity, including rape
any remark, behavior, or touch that signals a welcomed attraction
any unwanted remark, behavior, or touch that is sexual in nature
any unwanted behavior that will not affect the victim emotionally, but physically

Explanation:

Sexual harassment is defined as any unwanted behavior of a sexual nature. Forced sexual activity (including rape) is a criminal act of sexual assault, not just harassment. A welcomed attraction is not harassment. And sexual harassment can affect a victim emotionally and/or physically. So, the key is that it's unwanted and sexual in nature.

Answer:

any unwanted remark, behavior, or touch that is sexual in nature
