The correct answer is A. The massive Labrador Retriever

Explanation:

In grammar, a noun phrase refers to a set of words that can be a subject or object in a sentence. This type of phrases can be identified because they always include a noun  (word that names an object, animal, person or entity) or a pronoun (words such as she, he, it, etc that  replaces a noun) along with other words such as adjectives that describe or modify the main noun or pronoun. Considering this, the one from the options that is a noun phrase is "the massive Labrador Retriever" because this phrase includes one main noun "Labrador Retriever" along with an adjective or modifier to describe "massive" which are two of the main features of noun phrases, also this phrase can be a subject or object. On the other hand, other options do not include a noun and can not act as a subject or object in a sentence and therefore cannot be noun phrases.
