The answer is: C) direct characterization.
Direct characterization occurs when the narrator particularly exposes the attributes of a character in a direct manner.
In the quotes from "The First Tears," Amak 's personality, reactions and emotions are described explicitly by the author. For example, his feelings of hunger, his joy when seeing the animals, and his annoyance when the seals swim away.
The rest of the options are incorrect because indirect characterization is when the author reveals a character's personality through speech, actions and appearance; and a flat character is a simple one who does not evolve during the development of the story.
