From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.

One of the muggers who snatched the hangbag _____ been arrested by the police. 

Answer Details

The correct answer is "has." The sentence is in the present perfect tense, indicating an action that started in the past and is still relevant in the present. The word "has" is the helping verb used in the present perfect tense. In this sentence, the subject is "One of the muggers," which is singular. Therefore, we need a singular form of the helping verb "have." The only option that provides a singular form of the helping verb "have" is "has." So the sentence should read, "One of the muggers who snatched the hangbag has been arrested by the police."
