Solution
The correct option is C Echinopluteus
The fertilized egg of 'sea urchin', once met with the free-floating sperm released by males, develops into a free-swimming blastula embryo. Initially a simple ball of cells, the blastula soon transforms into a cone-shaped, echinopluteus larva. This larva has 12 elongated arms lined with bands of cilia that capture food particles and transport them to the mouth. Hence, option C is correct.
