Correct option is D
The given sentence is:
Aren't you older than your sister?
This is a negative interrogative sentence, which is asking a question using a contraction of "are not" (aren’t).
Let’s break it down:
"Aren’t" = "Are not"
The structure is Are not you older than your sister?
This question implies an expectation that you are older than your sister, and the speaker is confirming it.
To convert a question into a statement, we:
Remove the auxiliary verb and subject inversion.
Make the sentence positive unless the question is genuinely negative in meaning.
So,
"Aren't you older than your sister?" → "You are older than your sister."
This matches Option (d).
