Answer
Both A and R are True.
Reason — Ptyalin is secreted by salivary glands. Amylopsin is secreted by the pancreas into the small intestine. Despite being secreted from different glands, both enzymes perform the same function: they break down starch into maltose. Both enzymes catalyze the hydrolysis of starch (a polysaccharide) into maltose (a disaccharide).
