C
fructose
D
galactose
Explanation: 

Detailed explanation-1: -Final answer: Sucrose is not a monosaccharide.

Detailed explanation-2: -Sucrose, glucose and fructose are all simple carbohydrates or simple sugars. Glucose and fructose are individual sugar units and are also called monosaccharides. Sucrose is a sugar molecule made up of both glucose and fructose so sucrose is called a disaccharide.

Detailed explanation-3: -Sugars are categorized as monosaccharides or disaccharides. Disaccharides are made up of two linked monosaccharides and are broken back down into monosaccharides during digestion ( 1 ). Sucrose is a disaccharide consisting of one glucose molecule and one fructose molecule, or 50% glucose and 50% fructose.

Detailed explanation-4: -Sugars are carbohydrates that are chemically classified as monosaccharides and disaccharides.

Detailed explanation-5: -The three main monosaccharides that we consume are fructose, galactose and glucose. These monosaccharides combine in various pairs to form the three disaccharides that are most important in human nutrition: lactose, maltose and sucrose. The monosaccharide glucose is the common thread in each of these disaccharides.
