Model Answer

Option B — Error: at | Correction: in
The correct preposition with "school" as an institution is "in school," not "at school."

Explanation

"In school" refers to being enrolled as a student (institutional sense). "At school" refers to physical location. In this context, the sentence means kids were students, so "in school" is correct. Examiner expects you to identify both the error word and the replacement precisely.
