Correct answer: C. Swallow it whole with water
- A. Crush it and mix it with water
- B. Chew it thoroughly before swallowing
- C. Swallow it whole with water

Explanation
An enteric coating protects the drug from stomach acid or protects the stomach from the drug, so the tablet should be swallowed whole. Crushing, chewing or dissolving it can destroy the intended release and protective action.
