  • Correct answer
    A
    nitrogen containing polysaccharide
  • B
    phosphorus containing polysaccharide
  • C
    sulphur containing polysaccharide
  • D
    simple polysaccharide

Solution

Macromolecule chitin is a complex polysaccharide containing amino sugars and chemically modified sugars (e.g., glucosamine, $\mathrm{N}$-acetyl galactosamine, etc). Polysaccharides are long carbohydrate molecules of monosaccharide units joined together by glycosidic bonds. They have a general formula $\mathrm{C}_x\left(\mathrm{H}_2 \mathrm{O}\right)_y$.

Hence, the correct answer is option: 'A'.
