Answer:
The correct answer is A. noun.
Step-by-step explanation:
We can determine which type of phrase a certain group of words is based on the central word. If the central word (or center, for short) is a noun, then it's a noun phrase; if it's an adjective, then it's an adjective phrase, and so on.
In the example above, the center of the phrase is the noun car because everything else in the phrase is describing it. You can ask the question - What kind of a car?, and the answer would be - (the car) with the red racing stripe.
This will help you determine the center of the phrase. And since the center word car is a noun, that means that the entire phrase is a noun phrase.
