Choose the word that best completes the sentence.

One of the girls left _____ tennis shoes in the gym.

a. her***
b. hers
c. their
d. them

Her

The correct answer is a. her.

To choose the word that best completes the sentence, we need to determine the correct possessive pronoun to refer to the "girls."

In this case, we are looking for a pronoun that indicates ownership and agrees with the noun "girls."

The correct answer is "a. her."

To arrive at this answer, consider first that the subject of the sentence is "One of the girls." Since there are multiple girls and we refer to only one of them, we need to use a singular possessive pronoun. Among the given options, "a. her" is the correct singular possessive pronoun that matches with "One" and indicates ownership of the shoes. The word "her" shows that the tennis shoes belong to one of the girls.
