B, Sugars are monomers that make up starches.
Explanation - Sugars are the carbohydrates. The monomeric unit of these sugars is called as monosaccharides. Example of monosaccharides are - glucose, galactose. These monomers combine in specific numbers to form polysaccharide.
Starch is a polysaccharide that has glucose as its monomeric unit. α-1,4-glycosidic bond is the linkage formed between the glucose while forming starch. In plants, photosynthesis leads to the formation of glucose which gets converted to starch and the food is stored in the form of starch and not glucose.
