Correct Answer & Explanation
Option A
• For an assertive sentence, 'said' remains 'said' if there is no object, and the connector 'that' is used.
• The first-person pronoun 'I' changes to 'he' (referring to 'my friend').
• The present perfect tense 'have never seen' changes to past perfect 'had never seen' because the reporting verb 'said' is in the past tense.
