The correct option is
B (b) Fructose
Explanation for correct option:
Option (B) Fructose
- Fructose, often known as fruit sugar, is a ketonic simple sugar present in many plants.
- It is frequently linked to glucose to produce the disaccharide sucrose.
- Inulin is a fructose polymer found in many plants.
- It is found in the roots and rhizomes of plants. Inulinase is produced by hydrolysis of inulin.

Explanation for incorrect options:
Option (A) Glucose:
Glucose has a chemical formula and is a simple sugar.
Option (C) Galactose:
- The most frequent monosaccharide is glucose, but galactose is more typically found in the disaccharide, lactose, or milk sugar.
- It is found in peas as a monosaccharide.
- Galactose is a glucose isomer.
- They simply differ in the arrangement of their atoms.
- Glucose and galactose are stereoisomers.
Option (D) Arabinose:
Arabinose is an aldopentose, which is a monosaccharide with five carbon atoms and an aldehyde () functional group.
Thus, option (B) is correct. Inulin is a polymer of Fructose.
