The answer is: B
Explanation
The correct option is B: sexual harassment.
Casting couch is a term that refers to the practice of demanding sexual favors from a job applicant in exchange for employment in the entertainment industry, primarily acting roles. This is a form of sexual harassment, which is defined as unwelcome sexual advances, comments of a sexual nature, requests for sexual favors, and harassment or comments about an individual’s gender, all of which create a hostile work environment.
Sexual assault, on the other hand, is an act in which one intentionally sexually touches another person without that person's consent, or coerces or physically forces a person to engage in a sexual act against their will. Sexual assault is a more severe form of sexual violence that includes rape, groping, and child sexual abuse.
Therefore, casting couch is an example of sexual harassment, not sexual assault, although some cases of casting couch may also involve sexual assault.
