In the sentence identify the segment which contains the grammatical error.
My brother, who live in Delhi, has written me a letter.

Options

A. who live in Delhi
B. has written
C. me a letter
D. My brother

Answer

A

Explanation

The given sentence is in the present perfect tense/have + V (3rd form of the verb)) so it will have the present form of the verb(live) and not the past form(lived). However, .brother. is a singular subject so it will take .lives. as a singular verb. Hence, .who lives will be answer.
