Answer 1

Correct option is (c) maltose, maltase

To explain: Maltose is a diasaccharide which is made of two molecules of glucose. Maltase is secreted by the small intestine and it breaks down maltose into two glucose. Lactase breaks lactose into glucose and galactose while sucrase breaks sucrose into glucose and fructose.
