Final answer:
The irony in Tara's situation in the play is that only the audience knows that Kul wants to go out with her. Hence the correct option is D.
Step-by-step explanation:
The best explanation for the irony in Tara's situation in this play is option D: Only the audience knows that Kul wants to go out with Tara. Irony is a literary device that involves a contradiction between what is expected and what actually occurs. In this case, the irony lies in the fact that Tara is unaware of Kul's feelings, while the audience is privy to this information. This creates a sense of dramatic irony, as the audience knows something that the character does not. By choosing option D as the best explanation, we recognize that the irony in Tara's situation is dependent on the audience's knowledge.
