Choose the sentence in which the italicized pronoun agrees in number with its italicized antecedent orantecedents.
a. the waiter refilled their glasses as they emptied it. b. the boys want their dessert now. c. mary and jill won't eat her vegetables. d. maureen called the children for her meal.

B). The boys want their dessert now.

Explanation:

As per the question, option B i.e. 'The boys want their dessert now' exemplify the sentence that involves an agreement between the pronoun and the italicized antecedent/antecedents/. In this sentence, the plural pronoun 'the boys' agrees with the italicized antecedent 'their'(plural) in number that appropriately justifies the pronoun-antecedent agreement which proposes that the pronoun and its antecedent must follow the same number(agree in number). The other options do not show this agreement(in option A 'the waiter'(singular) disagrees to the plural 'their', in options C and D also, plural pronouns 'Mary and Jill' and 'children' are wrongly paired with singular antecedent 'her'). Thus, option B is the correct answer.
