Show answer & explanation
Correct answer: A
Explanation
To convert indirect speech to direct speech, the tense of the verbs needs to be adjusted back to the present. The indirect verb 'told' becomes 'said', 'must tell' remains the same as it is a modal verb, 'had seen' changes to 'saw' (past tense for direct speech), 'that morning' changes to 'this morning', 'it could be' remains 'it could be', and 'had been haunting' changes to 'has been haunting'.
