Which sentence demonstrates correct subject-verb agreement?

• A. The group of students walks to the library.
• B. The group of students walk to the library.
• C. The groups of students walks to the library.
• D. The group of student walks to the library.

Answer: (A)

Subject-verb agreement means the verb must match the subject in number. Here, the main subject is The group, which is singular, even though it’s followed by the prepositional phrase of students. With a singular subject, the verb in present tense takes the -s form, so walks is the correct choice. The other sentences either use a plural verb form (walk) that doesn’t agree with the singular group, or change the subject to groups (which would require walk), or use an incorrect noun in the prepositional phrase (student instead of students). So, The group of students walks to the library shows proper agreement.
