Which pronouns are used as the subject or part of the subject of a sentence?

Subject pronouns are the correct choice because they perform the action of the verb in a sentence and indicate who or what is doing that action. Examples of subject pronouns include "I," "you," "he," "she," "it," "we," and "they." When used in a sentence, these pronouns take the place of a noun and can adequately stand as the subject.

For instance, in the sentence "She runs every morning," "She" is a subject pronoun serving as the subject of the verb "runs." This highlights the pronoun's crucial role in conveying the action's subject in a clear and concise manner. Understanding subject pronouns is vital for constructing grammatically correct sentences and enhancing language fluency.
