The correct option is D Both A and B

Visceral hump is also called as visceral mass. It is present within the shell of molluscs. Mantle cavity and ventral side of foot possess visceral hump. It holds the digestive, reproductive, excretory and respiratory systems. The visceral hump also includes the mantle which consists of two flaps that secrete the material that forms the shell and protects mantle cavity. The mantle cavity contains the gills, which excrete waste and circulate oxygen.
