Which type of pronoun includes the words: he, she, and they?

The correct choice refers to subject pronouns, which are used as the subject of a sentence to indicate who is performing the action of the verb. The words "he," "she," and "they" are classic examples of subject pronouns because they directly take on the role of the subject. For example, in the sentences "He runs," "She sings," and "They dance," these pronouns clearly show who is doing the action.

In contrast, object pronouns serve a different function; they receive the action of the verb. Reflexive pronouns are used when the subject and the object of the verb are the same, such as in "He taught himself." Possessive pronouns indicate ownership, such as "his," "her," and "their." Understanding the role of each type of pronoun is key to mastering sentence structure and clarity in writing.
