Examples of which biological macromolecule include glucose, fructose, starch, and glycogen?
A
Lipids
B
Carbohydrates
C
Nucleic Acids
D
Proteins
Explanation: 

Detailed explanation-1: -Polysaccharides may be very large molecules. Starch, glycogen, cellulose, and chitin are examples of polysaccharides. Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose).

Detailed explanation-2: -Common monosaccharides include glucose and fructose. Image adapted from OpenStax Biology. The polymers are called polysaccharides, and they are long chains of monomers or monosaccharides. Common polysaccharides include carbohydrates for energy storage like starch in plants and glycogen in animals.

Detailed explanation-3: -Glucose is a hexose, a sugar composed of six carbon atoms, usually found in ring form. A starch macromolecule is a polysaccharide composed of thousands of glucose units.
