Correct Answer & Explanation
Option C
• For interrogative sentences, 'said' changes to 'asked' or 'inquired'. Since there's an implied listener ('you'), 'asked me' is appropriate.
• The Wh-word 'when' acts as the connector.
• The sentence structure changes from interrogative to assertive (subject + verb), so 'will you return' becomes 'I would return'.
• 'Will' changes to 'would' in indirect speech when the reporting verb is in the past tense.
• 'Your' changes to 'my' to match the new subject 'I'.
