Neither Carla nor Tim plays in the marching band is the sentence with the correct subject-verb agreement.
Explanation:
In the context of linguistics, the term agreement refers to words changing their form in a certain way that depends on the other words to which they relate.
According to the subject-verb agreement, the verb and the subject must agree in number. This means that, if the verb is singular, the subject must also be singular, and the other way around.
An example of the correct subject-verb agreement is the sentence Neither Carla nor Tim plays in the marching band. Even if there are two subjects in the given case, the verb is singular. When the subjects are both singular and are connected by the words or, nor, neither/nor, either/or, or not only/but also, the verb is also singular.
Sentence A is incorrect as we is a plural noun and should be used with the plural verb (are instead of be). Sentences B and C are similar. Sisters is plural, so instead of plays, the form play should be used. Frogs is also plural, and the correct form of the verb would be croak.
