Answer is Right!
Answer is Wrong!
The correct answer is A. The guests appreciated every dish which had been cooked by my mother.
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option B is incorrect because it does not specify that the dishes were cooked by my mother. Option C is incorrect because it does not specify that the guests appreciated the dishes. Option D is incorrect because it does not specify that the dishes were cooked by my mother.
The sentence “Every dish which had been cooked by my mother was appreciated by the guests” can be paraphrased as “The guests appreciated all of the dishes that my mother had cooked.” This means that the guests liked all of the dishes that my mother had cooked.
