The correct option is
B Ptyalin/amylase
The correct answer is B.
Amylase is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates into easier to absorb simple sugars. Salivary amylase is the first step in the chemical digestion of food. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose.
