Solution

The correct option is A a only
Maltose is an enzyme that catalyzes the hydrolysis of the glycosidic bond. Maltose can be broken down into glucose by maltase enzyme. Maltase secreted by the intestine converts maltose into glucose. They are called brush bordered enzymes because they involve in digestion and are embedded in microvilli.
So, the correct option is 'Maltose maltase Glucose +Glucose'.
