which of the following shows correct subject-verb agreement

a:Neither Jennifer nor her friends is interested in the free concert tickets

b:The garden club have planned the next plant fair.

c: Joe is one of the messengers who work for the law firm.

d: There goes my teachers and his new girlfriend.

B is correct. Always replace with pronouns and that makes it easier to see. The garden club = they, and you would say they have, so it's correct.

I'm sorry, Jen, but B is not correct. The club is considered as one unit. It has planned the next plant fair.

C. is the correct sentence. The subject of the verb "work" is "who" which refers to "messengers."

To determine which sentence shows correct subject-verb agreement, we need to pay attention to the agreement between the subject (the noun or pronoun that performs the action) and the verb (the action or state of being).

a: "Neither Jennifer nor her friends is interested in the free concert tickets."
In this sentence, the subject is "Neither Jennifer nor her friends," which functions as a unit. Since "Neither" suggests a negative correlation, the verb "is" correctly agrees with a singular subject, indicating that the singular subject is interested.

b: "The garden club have planned the next plant fair."
In this sentence, the subject is "The garden club." Although "club" is singular, the verb "have" is plural. The correct form should be "has" because the verb should agree with the singular subject. Therefore, this sentence does not show correct subject-verb agreement.

c: "Joe is one of the messengers who work for the law firm."
In this sentence, the subject is "Joe." The verb "is" agrees correctly with the singular subject. The phrase "one of the messengers who work for the law firm" is a modifying clause that does not affect the subject-verb agreement. Therefore, this sentence shows correct subject-verb agreement.

d: "There goes my teachers and his new girlfriend."
In this sentence, the subject should be "There," which is a singular pronoun. However, the verb "goes" is incorrect because it is used for plural subjects. Additionally, the phrase "my teachers and his new girlfriend" does not agree with the subject-verb agreement, as it combines plural and singular nouns. Therefore, this sentence does not show correct subject-verb agreement.

So, the correct sentence that demonstrates subject-verb agreement is option c: "Joe is one of the messengers who work for the law firm."
