Solution
The correct option is A Radial symmetry
Molluscs are organisms that exhibit bilateral symmetry. Their body can be divided into two equal halves along a single plane. Whereas, radially symmetrical organisms can be divided into equal halves by any plane passing through the central axis.
Molluscs are usually dioecious, that is, sexes are separate, there are separate males and females. They are oviparous as they lay eggs. Molluscs show indirect development. The life cycle of many molluscs includes a free-swimming larva called trochophore.
