Correct option is C
Option (c) contains an error.
Explanation: The verb "do" is incorrectly used with the singular subject "he." The correct verb should be "does" to match the singular subject.
Grammatical rule used: Subject-verb agreement: Singular subjects (like "he") require singular verbs (like "does").

Incorrect: He
do not agree with them.
Correct: He
