Answer:
The answer is sadomasochism (Option A)
Explanation:
To begin with, It is important to know that Sadomasochism comes from the combination of two words sadism (hurting people) & masochism (being hurt).
Sadomasochism is a word that describes the kind of sexual activity (let's say between two people for better understanding) in which one of the participants enjoys inflicting mental suffering or pain on his/her sexual partner while the other participant or sexual partner who pain is being inflicted on derives sexual pleasure from experiencing the pain.
