Answer:
D. indirect characterization
Explanation:
Characterization is a literary device that authors use to develop fictional characters in a story, that is to say, to reveal a character's physical appearance, personality, interests, or motifs. This characterization can be either direct or indirect. When it is direct, writers directly tell readers how the character is, in other words, they make direct statements about the character personality, for example: "He was a tough and introvert guy, that's why he didn't talk much."
However, when the characterization is indirect, writers show the character's personality through dialogues, thoughts, behaviors, actions, the description of their appearance and people's reaction to the character. And this is the type of characterization that the text is using: the author does not make a direct statement about Harry, instead, they show how he is and how people sees him by describing his outfit, expressions, and usual behaviors.
