My friend asked me if my father had returned from Calcutta.
My friend told me that his father had returned from Calcutta.
My friend enquired me if his father had returned from Calcutta.
Answer is Wrong!
Answer is Right!
The correct answer is B. My friend asked me if my father had returned from Calcutta.
A is incorrect because the friend is asking a question, not making a statement.
C is incorrect because the friend is asking about my father, not his own father.
D is incorrect because the friend is asking a question, not making a statement.
The friend’s question can be paraphrased as “I don’t know if your father has returned from Calcutta. Do you know?”
