In the following question, a sentence is divided into four parts. Choose the part of the sentence which may contain a grammatical error in it. If all the parts of the sentence are grammatically correct and contextually meaningful, choose option “No error” as the answer choice. One of the students (A)/ have failed (B)/ in the examination (C)/ this year. (D)

Explanation

The error lies in part (B) of the sentence. Grammatical Rule: When a sentence starts with 'One of the,' the following noun is always plural, but the verb is always singular because the actual subject is 'One.' In this sentence, the subject is 'One,' which is singular, so the plural verb 'have' must be replaced with the singular verb 'has.' Correct Sentence: One of the students has failed in the examination this year. So the correct answer is (b)
