The Correct Option is B

Solution and Explanation

The exoskeleton of Arthropods is made up of Chitin.

(A) Hyaluronic Acid - Incorrect: This is a component of animal connective tissue, not exoskeletons.

(B) Chitin - Correct: Arthropod exoskeletons consist of chitin, a nitrogen-containing polysaccharide.

(C) Waxes - Incorrect: While waxes may coat the exoskeleton, they're not its structural component.

(D) Cellulose - Incorrect: This is the plant cell wall component, not found in arthropods.

The correct answer is (B) Chitin, the characteristic tough polysaccharide in arthropod cuticles.
