Final answer:
Sucrase is an enzyme that breaks down sucrose (table sugar), a carbohydrate, into glucose and fructose.
Step-by-step explanation:
Sucrase is an enzyme that breaks down sucrose, which is a type of carbohydrate. Sucrose, also known as table sugar, is a disaccharide that, when hydrolysed by sucrase, is split into two monosaccharides: glucose and fructose. These monosaccharides can then be readily absorbed by the small intestine and used in metabolic pathways to provide energy for the body. Therefore, the answer to the question is (b) Carbohydrates.
