Which of the following sentences contains subject-verb agreement?

The sentence "Jerry and Karen, the new nurses on the floor, rush to the nurse's station" demonstrates correct subject-verb agreement because the subject "Jerry and Karen" is plural. When there are two or more subjects joined by "and," the verb must also be plural to match the subject. In this case, "rush" is the plural form of the verb, aligning appropriately with the plural subject.

Additionally, the other options show discrepancies in subject-verb agreement. For example, when "Jerry and Karen" is treated as a singular subject in one choice, or when a singular verb form is used incorrectly with a plural subject in another, these choices illustrate a misunderstanding of how to correctly match subjects and verbs in terms of number. The correct usage in choice B reinforces the essential rule of subject-verb agreement, making it the appropriate selection for this question.
