Answer is Wrong!
Answer is Right!
The correct answer is D. No error.
The sentence is grammatically correct. The word “why” is used to
introduce a clause that asks for a reason. The word “in negative” is used to describe the way in which someone replied. The word “when” is used to introduce a clause that describes the time at which something happened.The sentence can be paraphrased as follows: “I do not understand why he replied in the negative when the proposal was in his favour.”
