Answer: I would contend that the right answer is actually the D) by expressing the speaker's sarcasm.
Explanation: Just to elaborate a little bit on the answer, it can be added that by using a rhyming and concise couplet, the author, the brilliant African American poet Phillis Wheatley (1753-1784), was able to very effectively call attention to her sarcastic words, which apparently attempt at praising, but were truly aimed at mocking, King George III, who was King of England during the American Revolution. This poem was, in fact, a harsh criticism of the monarch and the economic burden he imposed on the American colonies.
