D. They face problems with love.
The answer is B, Incendiary
Answer:
The theme of the story is "trusting family and friends when you need them"
It is easy to identify the theme, since the main character goes through an ordeal when he gets lost; however, relying on a friend lets him find the way out of the situation.
Building long-life relationships is also shown in the story as a virtue, since the character had a shy personality and it was really hard for him to make friends.
