Three examples of Monosaccharides are glucose, ribose, and fructose.

Three examples of disaccharides are lactose, sucrose and maltose.

Three examples of polysaccharides are starch, glycogen and cellulose.

Explanation: Monosaccharides are simple sugars that contains only one sugar molecule. A monosaccharide can be a triose, a tetrose, a pentose, a hexose and a heptose containing three, four, five, six and seven carbon atoms respectively in their backbones.

Disaccharides are sugars that contains two sugar molecules joined by a glycosidic bond. Example is sucrose which contains two six carbon sugars: D-glucose and D-fructose.

Polysaccharides are sugars containing more than twenty monosaccharide units, joined by different types of glycosidic bonds. Polysaccharides differ from each other by the type of monosaccharide units they contain, the length of their chains, the types of bonds joining the units and in the extent of their branching.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
