Answer is Right!
Answer is Wrong!
The correct answer is: D. they aren’t
The question is “Are Peter and Mary still sitting in the office?” The answer is “No, they aren’t.” This means that Peter and Mary are not sitting in the office. They may be standing, walking, or doing something else.
The other options are incorrect because they do not accurately reflect the answer to the question. Option A, “they don’t sit,” is incorrect because it does not say where Peter and Mary are. Option B, “they standing,” is incorrect because it does not say that Peter and Mary are not sitting in the office. Option C, “there aren’t,” is incorrect because it does not say who is not in the office.
