Answer:
Internal conflict
Step-by-step explanation:
In this story, we see that the protagonist is experiencing a type of internal conflict. This occurs because the protagonist is experiencing two opposing desires, and cannot decide which one to follow. An internal conflict is a conflict that occurs in a character's mind. In this example, the protagonist feel guilty because of the fact that his grandmother is mistaking him for her late husband. On the other hand, he does not feel strong enough to correct her, as he does not want to hurt her. These two opposing views create conflict in the character's mind.
