Select the most appropriate option that can substitute the highlighted segment in the given sentence.
He was sitting besides his best friend during the event.

Correct option is C

The correct substitution of the highlighted words is (c) was sitting beside his.
Explanation:
· "Besides" means "in addition to," which is wrong here.
· " Beside" (without 's') means "next to" or "at the side of," which fits the sentence properly as it talks about physical positioning.
