Subject-Verb Agreement
In this sentence, the subject is "chairs and tables" and the verb is "are." The verb "are" is the present tense form of the verb "to be" and agrees with the plural subject "chairs and tables." Therefore, the correct answer is option C, "are."

Subject-Verb Agreement Rules:
1. Singular subjects take singular verbs, while plural subjects take plural verbs.
2. When the subject is a compound subject joined by "and," it is usually plural and takes a plural verb.
3. When the subject is a compound subject joined by "or" or "nor," the verb agrees with the subject closest to it.
4. If the subject is a collective noun (e.g., team, family, class), the verb can be singular or plural depending on whether the collective noun is acting as a unit or as individuals.
5. Indefinite pronouns like "everyone," "everyone," "someone," "nobody," etc., take singular verbs.
6. The verb "to be" (am, is, are, was, were) is conjugated differently based on the subject.

In this sentence, the subject "chairs and tables" is a compound subject joined by "and." As per rule 2, compound subjects joined by "and" are usually plural and take a plural verb. Therefore, the correct verb form is "are."

Other Options:
- Option A, "is," is incorrect because it is the singular form of the verb "to be" and does not agree with the plural subject "chairs and tables."
- Option B, "was," is incorrect because it is the past tense form of the verb "to be" and does not match the present tense context of the sentence.
- Option D, "were," is incorrect because it is the past tense form of the verb "to be" and does not match the present tense context of the sentence.
