Select the most appropriate option to fill in blank number 3.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. who.
Context:
The sentence is describing a boy named Mohit and then gives additional information about him — specifically, where he sits in class. The blank is before "sits behind me in biology," and we need a relative pronoun to refer to "the kid."
Correct word: Who
Reason: The clause requires a subject pronoun for the verb sits. “The kid” is a person, so the correct subjective relative pronoun is who.
Hence, the chosen option will be correct.
