I think the correct answer among the choices listed above is option B. Chitin, in arthropods, is a structural carbohydrate that forms their exoskeleton. It is a long chain of polymer of an N-acetylglucosamine. Hope this answers the question. Have a nice day.
Answer;
-Chitin is a structural carbohydrate that forms their exoskeleton
Explanation;
-Chitin is the main component in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi.
-It is a linear long chain polymer consisting of repeated units of N-acetyl-glucosamine.
-The main function of the chitin-containing exoskeleton is to keep the inner soft tissue safe from any sort of injury and also prevents the delicate tissues from drying (acts as a water tight barrier against dehydration).
