Simple sugar, a carbohydrate that cannot be decomposed by hydrolysis
A
Polysaccharide
B
Monosaccharide
C
Disaccharide
D
Nucleic acid
Explanation: 

Detailed explanation-1: -Monosaccharides are carbohydrates that cannot be hydrolyzed to simpler carbohydrates. These compounds may be aldehydes or ketones, or acetals or ketals which yield an alcohol and a monosaccharide when hydrolyzed.

Detailed explanation-2: -Because monosaccharide is the simplest unit, it cannot be hydrolyzed into simpler molecules. Hydrolysis of disaccharides, polysaccharides, and oligosaccharides to monosaccharides is possible.

Detailed explanation-3: -Ribose is a sugar which cannot be hydrolyzed further as it is a smaller sugar with 5 carbon. Maltose, Sucrose, and Lactose are complex sugar which can be hydrolyzed into a smaller unit of sugars.
