Correct Answer is D
Explanation
Stomach pH, food in the stomach, and blood flow to the gastrointestinal tract can all affect the absorption of orally administered drugs. For example, some drugs require an acidic environment for optimal absorption and may be affected by changes in stomach pH.
Food in the stomach can delay gastric emptying and slow down drug absorption.
Blood flow to the gastrointestinal tract can affect drug absorption by altering the rate at which drugs are delivered to the absorption site.
a. Stomach pH alone can affect drug absorption, but it is not the only factor.
b. Food in the stomach alone can affect drug absorption, but it is not the only factor.
c. Blood flow to the gastrointestinal tract alone can affect drug absorption, but it is not the only factor.
