Which sentence uses inclusive, gender-neutral pronoun usage for a singular antecedent?

• A. Each student must submit his or her assignment.
• B. Each student must submit their assignment.
• C. Each student must submit him assignment.
• D. Each student must submit she assignment.

Answer: (B)

Inclusive, gender-neutral pronouns for a singular antecedent focus on pairing the pronoun with a single person without assuming gender. When the subject is “each student,” the sentence can use the singular they to stay inclusive while keeping number agreement intact. Therefore, “Each student must submit their assignment” is the best choice because their acts as the possessive pronoun referring to one person, but without tying it to a specific gender. It reads smoothly and aligns with modern usage that treats singular they as appropriate for unknown or non-binary individuals.

The other options mix in gendered pronouns or break grammatical norms: using “his or her” is not inclusive in everyday practice, and “him assignment” or “she assignment” are ungrammatical with a singular subject.
