Answer:
C. Reeve's remarks have not been polite
Step-by-step explanation:
Verbal irony is a figure of speech used when a person says the opposite of what they mean. This can be explicit or deducible from the context of the speech or conversation. In the context of the speech between Reeves and his mom Opal, the first question by his mom was a verbal irony as the succeeding narration indicates.
Opal's question, "Could you be any more polite?" is ironical because Reeves was never even polite in the first place. It is interesting to use verbal irony when writing because it helps the reader to apply his sense of reasoning, and appreciate the author's use of words.
