Answer:
C. Dry bones.
Explanation:
A noun phrase is a group of words along with a noun that acts as a noun in a sentence. This means that aside from a single noun, a noun phrase contains other details that describe the said noun and acts as a nominal or noun in the sentence.
In the given options, the only option that contains a noun is in the third option with the words "dry bones" where the word "bones" is a noun. And the word "dry" describes the "bones", thereby acting or adding to the noun. This way, the two words "dry bones" act as a noun together and thus, become a noun phrase.
Thus, the correct answer is option C.
