"The Importance of Being Earnest" is the most famous comedy of manners of all time. A comedy of manners satirizes society, criticizing social standards and manners. There is usually a love affair or some other sort of scandal in the plot. The dialogs are full of witty remarks and sarcasm.
As for the options, letter C is the one that best supports the affirmation that this play is a comedy of manners. It's a remark made by the character Miss Prism, who has a love interest in Reverend Chasuble. She tries to convince him that he should marry, that a single man is a constant temptation to women. By marrying, according to her, he would be doing what is best for the Church. She goes on to say that older women would be a better choice (she is an older woman). Wilde probably used her character to criticize the desperation of older women of that era when it came to marriage.
