Correct Answer & Explanation
Option A
• The reporting verb 'said' remains 'said' as there is no object. (Assuming 'you' refers to 'me' for pronoun change).
• The conjunction 'that' is used.
• The modal verb 'will' changes to 'would' in indirect speech when the reporting verb is in the past tense.
• The pronoun 'I' changes to 'he' (subject of reporting verb).
• The time adverb 'tomorrow' changes to 'the next day' or 'the following day'. So, options B, C, and D are incorrect for various reasons (incorrect tense, pronoun, or time adverb).
