Explanation: a participle is a word formed from a verb and used as an adjective or a noun. In English participles are also used to make compound verb forms. The participle form of the verb "to do" is irregular and it is "done" so the correct answer is the corresponding to option D: has done. The complete sentence would be: The stranger has done this town a great service.
