One of the girls left jacket in the cafeteria.

Choose the pronoun that agrees with the italicized antecedent in number and gender.

A) his

B) her

C) hers

D) their

B) her

Explanation:

Pronouns are used to indicate possession. Possessive pronouns are used in place of a noun while possessive determiners are placed before a noun.

Possessive determiners:

his

her

Possessive pronouns:

his

hers

In this case, the italicized antecedent refers to a girl (one of the girls), and the sentence refers to a jacket she possesses, so the correct pronoun would be the possessive determiner 'her.'

because each is self-sufficient.
