Answer:
D) xray.
Explanation:
Hyphen is a form of punctuation mark in a sentence or group of words or even a word that needs to be joined. They are used to separate syllables of a single word.
Hyphens are used to show a connection in the words that are joined but kind of separated by it.
While the other words - coordinate, extraordinary and noncompliance need not be hyphenated, the noun x- ray has to be divided or separated by the hyphen to make it a correct word.
