The following sentence has been divided into four parts. Identify the part that contains
an error.
(A) One of / (B) my brothers write / (C) novels for / (D) leisure.

Correct option is C

The error lies in part (B). The subject of the sentence is "One of my brothers," which is singular. Therefore, it requires a singular verb "writes" instead of the plural verb "write."
· Subject-Verb Agreement: When the subject of a sentence is a singular noun or pronoun, the verb must also be singular. In this case, "One of my brothers" is a singular subject, so the verb should be "writes."
· Correct sentence: One of my brothers writes novels for leisure.
