Answer:
C. Action
Explanation:
Characterization is a literary device that authors use to develop fictional characters in a story through their description. This characterization can be either direct or indirect. When it is direct, writers directly label a character as something or directly mention their traits, and when it is indirect, authors show the character's personality through dialogue, thoughts, behaviors, actions, and appearance.
The given sentence uses indirect characterization to describe the character, more specifically, it is using action because it is describing Ted's gesture while waiting for the dentist to arrive, in other words, it is describing what the character is doing. This description helps us infer something about him and his personality: He does not feel comfortable with the dentist's arrival, or with the waiting on the dentist's arrival.
