Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. the class doesn’t know.
- The original sentence, "The monitor of the class don't know the answer," contains a subject-verb agreement error.
- "Monitor" is a singular noun, so the verb should be in the singular form, which is "doesn't."
- Therefore, the corrected sentence is "The class doesn’t know the answer."
