B
disaccharide
C
polysaccharide
D
polypeptide
Explanation: 

Detailed explanation-1: -Polysaccharides (/ˌpɒliˈsækəraɪd/), or polycarbohydrates, are the most abundant carbohydrates found in food. They are long-chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages.

Detailed explanation-2: -Polysaccharides. A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide (poly-= “many”). The chain may be branched or unbranched and may contain different types of monosaccharides.

Detailed explanation-3: -Polysaccharides are major classes of biomolecules. They are long chains of carbohydrate molecules, composed of several smaller monosaccharides.

Detailed explanation-4: -Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide unit bound together by glycosidic linkage. Example: starch, glycogen, cellulose, chitin etc. On hydrolysis, they yield monosaccharide units which are usually similar.

Detailed explanation-5: -Glycogen is a polysaccharide made of long chains of glucose.
