Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

Subject-verb agreement is a fundamental rule in grammar that ensures a verb corresponds correctly with its subject in terms of both number and person. The term "number" refers to whether the subject is singular (one) or plural (more than one). For example, in the sentence "The cat runs," the singular subject "cat" requires the singular verb "runs." Conversely, in "The cats run," the plural subject "cats" requires the plural verb "run."

The term "person" pertains to the grammatical distinction between the speaker, the listener, and those being spoken about. In English, there are three persons: first person (I, we), second person (you), and third person (he, she, it, they). Each person has specific verb forms: "I run" (first person singular) vs. "they run" (third person plural).

Given this understanding, option C, "number and person," accurately encapsulates the two dimensions necessary for proper subject-verb agreement. In summary, maintaining agreement in both number and person ensures clarity and grammatical accuracy in communication.
