Answer:
Verb.
Step-by-step explanation:
In the given sentence, the italicized word is "wound" which can be taken in two ways. One is a noun that refers to a physical injury while the second is a verb that means to inflict pain or hurt to a person.
But in the sentence, the word is used to refer to the act of tying in a spiral pattern. This act of tying is an action verb, thereby making it a verb. The word "wound" as used in the sentence is the past tense form of the verb "wind".
So, the correct answer is a verb.
