Explanation

The Prophet Muhammad (ﷺ) showed respect for the funeral of a polytheist as part of his general conduct. Option B is incorrect because while he interacted with Jews, this specific act is not recorded as being done only for them. Option C is incorrect because there is no specific narration confirming this action was limited to Christians. Option D is correct because historical accounts suggest respect was shown across different groups, making 'None of these' the most accurate general answer if a single group isn't specified.
