Answer:
Aggressive behavior
Explanation:
The reason is that aggressive behavior is the exhibition of desires by ignoring the feelings and discomfort which is the caused by the exhibition of desires, which is the case in the given scenario. Lily has ignored the feelings and discomfort of her co-worker and despite Gracie's issues she has enforced her to obey her. So this behavior of Lily best represents Aggressive Behavior.
Furthermore, if Lily had preferred the feelings of her co-worker then it can be said that she was exhibiting passive behavior, which is not the case here.
Lily can had develped a relationship with her co-worker by resolving the issue but she haven't tried to do that. Such type of behavior in which the person tries to resolve issues with other is often referred to as Assertive behavior. Again this also not the case here. So the only option which is correct is Aggressive Behavior.
