D. Enchiladas or spaghetti is for dinner tonight.
In a sentence, when one subject is in plural ("enchiladas") and the other is in singular ("spaghetti"), and they are connected by the words "or", "nor", "neither/nor", "either/or", or "not only/but also", the verb must agree with the subject that is closest to it. In this case, "spaghetti" is the one that is closest to the verb, thus, the verb must be in singular as well ("is").

B. Enchiladas or tacos is the answer
...............................................................................................................................................
The phrase that completes the sentence is D. 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.
