Final Answer :
D
Explanation :
Mantle is a distinguishing feature of mollusks. It is a fold of tissue that covers the mollusk's body and secretes a shell in most species. Arthropods have an exoskeleton, annelids lack a shell or exoskeleton, echinoderms have a calcified endoskeleton, and chordates have a dorsal nerve cord, not a mantle.
