Explanation:  C) The small intestine is the primary site of GI absorption of a drug, because of its very large surface area, across which drugs may diffuse. Acids are normally absorbed more extensively in the intestines that in the stomach even though the intestines have a higher pH. The higher the pH, the more alkaline; the lower the pH, the more acidic.
