The Correct Option is D

Solution and Explanation


Step 1: Understanding the Concept:

Dietary fiber consists of non-digestible carbohydrates classified by water solubility into soluble and insoluble fractions.

Step 2: Detailed Explanation:

1. Soluble Dietary Fibres: Readily dissolve or swell in water to form viscous gels, fermented by colon bacteria. Major examples include Pectins, gums, mucilages, and beta-glucans.
2. Insoluble Dietary Fibres: Do not dissolve in water; include cellulose, hemicellulose, and lignin.
3. Glycogen: Digestible animal storage polysaccharide.
4. Fructose: Digestible monosaccharide.

Step 3: Final Answer:

Hence, the soluble fibre component is Pectin, matching option (D).
