Answer: C) The title is helpful in establishing the play as a comedy of manners because it makes use of witty wordplay.
Step-by-step explanation:
This play by Oscar Wilde, follows the lives of John Worthing and Algernon Moncrieff who engaged in some deception in order to escape their social responsibilities and add excitement to their lives but things take a turn when those deceptions are discovered.
From the beginning of the play, we can tell that the play will be a comedy due to the response by Lane to Mr. Moncrieff when he asked Lane if Lane had been listening. Lane's response featured witty wordplay by sarcastically suggesting that listening to Mr. Moncrieff play was impolite.
