Final answer:
The detail that suggests indirect characterization of Mathilde is that even the Minister notices her at the party, which implies her noticeable presence and leaves readers to infer her traits. option B is correct.
Step-by-step explanation:
The question asks which detail is an example of indirect characterization of Mathilde. In literature, indirect characterization is the process by which an author shows a character's personality through their actions, thoughts, feelings, words, appearance, or other characters' responses, rather than through direct statements.
With the given options, the closest to indirect characterization is 'Even the Minister notices her at the party.' This detail suggests that Mathilde has a presence or quality that draws attention without stating explicitly her traits, thus allowing the readers to infer her character.
