Correct Answer & Explanation
Option A
• For an interrogative sentence, 'said to' changes to 'asked' or 'inquired'. So, option D is incorrect.
• Since it's a 'Yes/No' question, 'if' or 'whether' is used as a connector. So, option B is incorrect for using 'that'.
• The tense 'Do you know' (Simple Present) changes to 'he knew' (Simple Past) in indirect speech. So, option C is incorrect for 'knows'.
• The pronoun 'my' changes to 'her' (referring to 'She').
