In the sentence "Every student forgot his or her homework," what is the correct pronoun form?

• A. His or Her
• B. Their
• C. His
• D. Her

Answer: (A)

The main idea is pronoun agreement with a singular subject. Here, the subject is “Every student,” which refers to one person at a time, so the pronoun that replaces it must be singular. Using “his or her” keeps the reference gender-inclusive while matching the singular subject, so it correctly stands for any student—boy or girl. Using just “his” would leave out girls, and “her” would leave out boys. “Their” is plural and doesn’t align with the single student being talked about, even though some modern writing accepts singular they. So the form that fits the sentence and preserves clarity and inclusivity is “his or her.”
