Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

The sentence "The presence of students is important" illustrates a clear agreement between the subject and the verb. The subject of the sentence is "the presence," which is a singular noun, indicating a single entity. The verb "is" is also singular, perfectly matching the subject in number. This agreement is crucial in English grammar, as it ensures clarity and coherence in communication.

Option A, "subject differs from verb," is incorrect because the singular subject "presence" does not differ from the singular verb "is." Similarly, option C, "subject and verb do not go together," is misleading since they are indeed in harmony. Lastly, option D, "subject is in plural number," is not applicable either, as "presence" is singular, not plural.

Overall, the correct choice is B: "subject agrees with verb," as both elements are aligned in their singular form, demonstrating proper grammatical structure and clarity in the sentence. This agreement is fundamental for effective communication in English.
