Which sentence uses a pronoun as the subject correctly?

• A. They gave him to the teacher.
• B. She gave her book to the teacher.
• C. Her gave she book to the teacher.
• D. The teacher gave her book to she.

Answer: (B)

The subject of a sentence must be in the nominative (subject) form of the pronoun—the one that represents who is doing the action. In the sentence that uses a pronoun as the subject correctly, the subject is She, which is the proper nominative form. The structure is clean: She (subject) gave (verb) her book (what’s being given, with her as a possessive determiner) to the teacher (indirect object via a prepositional phrase). The other options mix up pronoun cases: using Her as a subject, using she as the object after a preposition, or using a non-nominative form in the subject slot. This is why the sentence with She as the subject stands out as correct.
