Answer:
C: "Their voluminousness of wristband, with an air of excessive frankness, should betray them at once." (Paragraph 8)
Step-by-step explanation:
This quotation suggests that the pick-pockets in the area can be recognized by their exaggeratedly large wristbands, which give them a noticeable and conspicuous appearance. The phrase "voluminousness of wristband" implies that their wristbands are excessively large or puffed up, drawing attention to their wrists. The mention of an "air of excessive frankness" further indicates that these pick-pockets may display a confident or bold attitude, which could make them stand out or appear suspicious to the narrator.
Therefore, option C best characterizes the pick-pockets based on the given quotations, as it emphasizes their distinct wristbands and the potential for their appearance to give them away as thieves.
