The correct option is A sclerites
The body of the cockroach is divided into head, thorax and abdomen.
Head is made up of six segments, the thorax is made up of three segments and the abdomen consists of ten segments. The entire body is covered by a chitinous exoskeleton which is divided into plates. Each segment of the body has a hardened plate-like structure called the sclerites.
