Which is described as 'Subjects and verbs must match in number'?

• A. Subject-Verb Agreement
• B. Sentence Structure
• C. Correct Form
• D. Conjunction

Answer: (A)

Subject-verb agreement means the subject and the verb must match in number. In English, a singular subject takes a singular verb and a plural subject takes a plural verb, so sentences stay clear and grammatically correct. For example, "The dog runs" shows a singular subject with a singular verb, while "The dogs run" shows a plural subject with a plural verb. This exact idea is what the description is pointing to. Other terms refer more to how sentences are built, general grammar forms, or the role of connecting words, but they don’t capture the specific rule about matching number between subject and verb.
