The correct option is C both a and b
The body of the cockroach is covered by a chitinous exoskeleton which is divided into plates called sclerites. Chitin is a polysaccharide which is made up of N-acetylglucosamine. Arthrodial or articular membrane is a thin and flexible membrane that joins the sclerites. It is a special feature of arthropods and facilitates flexible movements of the organism.
