Answer: (A), (B), (D)

The correct options are

Monosaccharides are the simplest form of carbohydrates. They consist of one sugar and are usually colourless, water-soluble, and need no digestion. Glucose, galactose and fructose are monosaccharides and share the same molecular formula: $C_6{H}_{12}{O}_6$. However, the arrangement of atoms is different in each of these three sugars.
