Directions: Find out which part of the given sentence has an error of grammar usage. If the sentence has no error, mark your answer as (D).

Who of the (A)/ following is the largest (B)/ fish in the world? (C)/ No error (D).

This is the correct option as this part of the sentence has the error. In the sentence, ‘’who” has been used. As a rule, ‘which’ is used to refer to other living beings such as animals, insects, plants and objects and “who” is used to refer to human beings, either male or female. Thus, the correct sentence should be, “Which of the following is the largest fish in the world?”
