সঠিক উত্তরঃD.
He demanded of me why I had beaten his dog
Explanation: The correct indirect narration is 'He demanded of me why I had beaten his dog' (Option D). It uses proper structure for indirect speech. Other options ('why had I', 'why I have had', 'why had I had') do not follow the rules of sequence of tenses and indirect narration. Note: Indirect narration rules include changes in tense, pronouns, and question forms.
