Solution
The correct option is A Basic
The pH is a scale used to specify the acidity or basicity of an aqueous solution. A pH less than 7 is acidic, greater than 7 is basic and 7 is neutral. The alkaline pH of the small intestine is due to the presence of sodium bicarbonate that is secreted by the pancreas. Also, bile secreted by the liver is responsible for the alkaline environment of the small intestine. Hence, the environment of the small intestine is basic, that is having pH between 7.5 to 8.5. Thus, the correct answer is option A.
