Answer: b) projection
Explanation:
According to psychoanalytic theory, projection happens when a person projects onto others his/her own feelings or beliefs. In fact, Abdul is the quarrelsome classmate and he's the aggressive one, because he's externalizing an internal conflict.
His classmates are most probably responding to his initial reactions.
Abdul will have to look into his actions and attitudes, try to change them and then see if this generates change into his classmates as well.
