Correct Answer & Explanation
Option A
• The reporting verb 'said to' changes to 'asked' for interrogative sentences. • Since it's a Yes/No question (no wh-word), 'if' or 'whether' is used as the conjunction. • The tense 'Have you finished' (Present Perfect) changes to 'I had finished' (Past Perfect) in indirect speech. • The sentence structure becomes assertive, so 'I' comes before 'had finished'.
