Question

Complete the following sentence so that the subject agrees with the verb.

Answer 1

Enchiladas or tacos is the answer

Answer 2

The phrase that completes the sentence is C. Enchiladas or spaghetti.

This phrase is the only one that keeps a correct subject- verb agreement since the second noun is uncountable, so it corresponds with the singular form of the verb be. While enchiladas is a plural noun, the noun that must match with the verb is the one that is nearer the verb, in this case, spaghetti.
