The correct answer is C. Primery. The correct spelling is "primary".

A. Disjoint is a word that means "not connected or joined together". B. Levy is a word that means "a tax or other compulsory contribution". D. Enema is a word that means "a liquid or gas introduced into the rectum or colon by means of a tube".

The word "primery" is not a real word. It is a misspelling of the word "primary".
