Answer: C. cutting and stacking wood for the family in the cottage.
As the monster develops and learns about the world, we learn that he is not all bad. The monster simply has not had anyone to teach him the difference between right and wrong. However, his heart is capable of good. One of the actions that proves this is the fact that the monster cuts and stacks wood for the family that lives in the cottage. He wants to do this simply out of kindness, and with no ulterior motive. This is an action that shows the monster's good side.
