Final answer:
Mrs. Peacock is questioning a statement through her inquiry, reflecting a need for further information or clarification in the context of a dramatic dialogue. Thus, the correct answer is that Mrs. Peacock questions the statement.
Step-by-step explanation:
The dialogue snippet provided from 'Scene 4' suggests that Mrs. Peacock is questioning a statement. This action is represented by her direct query, “What do you mean 'Which one of them?'” which indicates a need for clarification about a previous remark.

These excerpts highlight the interactions between characters in a narrative, showing moments of tension, intrigue, and the unfolding of the plot through their conversation. Characters are seen seeking clarification, expressing doubt, or revealing information to others through their questions and statements.
Therefore, the correct answer to the student's question is option (a): Mrs. Peacock questions the statement. This demonstrates her perplexity and the need for further explanation in response to what has been previously stated by another character.
