Answer:
C. Â Predicate nominative
Explanation:
A predicate nominative is a noun or pronoun that completes the linking verb, renaming, identifying, or explaining the subject.
The subject is what the sentence is about. It tells us who/what performs the action expressed by the verb or who/what is being described. The subject of the given sentence is the car.
The linking verb used in the given sentence is will be (to be in the future simple form). It can't be used on its own and needs to be completed by another word or phrase. In this case, that word is yours - a predicate nominative.
