It’s an adjective because it’s describing it
I think that its A because B and C doesn't make sense and D has nothing to do with the topic.
Answer:
Explanparagraph 1: noun phrase because it begins with the word the, and any phrase that begins with the word the is a noun phrase.
Paragraph 2: noun phrase because it begins with the word "two" and any phrase that begins with two, or five is a noun phrase.
Paragraph 3: not a noun phrase because it does not begin with a word that would make it a noun phrase.
Paragraph 4: not a noun phrase because it does not begin with a word that would make it a noun phrase
