Question

In the following sentence, four words or phrases have been underlined. Choose the word or phrase which is not appropriate in standard written English. If the sentence has no error, mark (5).

The police have (1) informed us that he was (2) one of those (3) who (4) they arrested last night. NO ERROR (5)

Answer 1

"Who" should be used to refer to the subject of a sentence ( the person completing an action) and "whom" should be used to refer to the object of a verb or preposition (the person receiving the actions of the verb).

Here, "who" is incorrect and should be changed to "whom" as it is the object of the sentence.
