Answer:
B. Direct Characterization
Step-by-step explanation:
Characterization is the description of the physical attributes, ways of thinking, and actions of a character in a story. Direct characterization is an explicit description of the personality of a character while Indirect characterization is a description of the character through his or her actions in the story.
The description is implied in this case, therefore, the reader reaches his or her conclusion about the character through his actions in the story. The description of Scylla in this text is a direct characterization because it explicitly states that Scylla is a monstrous person.
