Answer: A. internal conflict - man vs self
Explanation: This is an internal conflict because Timmy is struggling with his own feelings and emotions. He is frustrated with his mother, but this conflict is happening within himself, rather than between himself and another person or group. He is battling with his own feelings of disappointment, anger and possibly abandonment, rather than with his mother directly. This is a conflict within himself, or "man vs self" as it is referred to in literature. This type of conflict is internal and emotional, and often deals with the individual's struggles with themselves and their own emotions, beliefs, and values.
