Vedclass · Answer

(A) In $Gastropod$ molluscs, the early embryo is symmetrical with an anterior mouth and a posterior anus. However, during development, the visceral mass rotates $180^{\circ}$ relative to the head and foot, bringing the anus near the mouth; this process is known as torsion. As a result, the adult $Gastropod$ becomes asymmetrical.
