C. a-tergites, b-sternites, c-sclerties, d-articular membrane
D. a-sclerties, b-sternites, c-tergites, d-articular membrane

Answer

B

Explanation

The entire body is covered by a hard chitinous exoskeleton. In each segment, exoskeleton has hardened plates called sclerites (tergites dorsally and sternites ventrally) that are joined to each other by a thin flexible articular or arthrodial membrane.
