This question examines the understanding of noun phrases. A noun phrase is a group of words that functions as a noun. - **A. quickly run:** 'quickly' is an adverb and 'run' is a verb, so this is an adverb-verb phrase, not a noun phrase. - **B. with great care:** This is a prepositional phrase functioning as an adverbial modifier. - **C. the old wooden house:** This consists of a determiner ('the'), two adjectives ('old', 'wooden'), and a noun ('house'), making it a noun phrase. This is the correct option. - **D. because she was tired:** This is an adverbial clause because it begins with the conjunction 'because'. The correct answer is the one where the word group acts as a noun, and 'the old wooden house' fits this definition.
