Which of the following carbohydrates is a polysaccharide?

Explanation:
Polysaccharides are long polymers formed when many monosaccharide units are linked together by glycosidic bonds. Starch is a classic example because it is a plant storage polysaccharide made from glucose units arranged in long chains (amylose and amylopectin). Sucrose and lactose are disaccharides, each built from two sugar units, while glucose is a single monosaccharide. So starch stands out as the only polysaccharide among the options.
