Vedclass · Answer

(C) The asymmetry in Gastropoda is primarily caused by the process of torsion. Torsion is the rotation of the visceral mass,mantle,and shell $180^{\circ}$ with respect to the head and foot during larval development. This twisting results in the asymmetrical arrangement of internal organs,such as the shifting of the anus to a position above the head.
