Solution
The correct option is C Trochophore
Mollusca is the second largest phylum. It includes various creatures such as clams, oysters, snails and octopi. They share a distant common ancestor with the annelid worms, an evolutionary heritage suggested by their larval form called the trochophore larva, found in all molluscs and in certain marine annelids called polychaete worms.
Thus the correct answer is option C.
