Correct Answer & Explanation
Option D
Imperative sentences with 'Let':
• When 'Let' does not denote a joint proposal or suggestion (unlike 'Let us'), but rather seeks permission, the reporting verb changes to 'requested' or 'asked'.
• It is followed by an infinitive: 'to let him' or 'to allow him to'.
• Pronoun 'me' changes to 'him'.
• Thus, option D correctly translates the speech without incorrectly turning it into a mutual proposal.
