Correct Answer & Explanation
Option A
• For interrogative sentences, 'said to' changes to 'asked' or 'enquired of'.
• Since it's a Yes/No question, 'if' or 'whether' is used as the connector.
• The tense 'Did you finish' (Simple Past) changes to 'had finished' (Past Perfect) in indirect speech.
• The pronoun 'you' (second person) changes to 'he' (referring to her brother), and 'your' changes to 'his'.
