Solution
The correct option is B Annelids
Molluscs are very diverse but still show some similarity with the annelids because they share common ancestors, for example, their larval form, called a trochophore larva found in all molluscs and in certain marine annelids called polychaete worms. Both molluscs and annelids probably evolved from free-living flatworms. Both are triploblastic and bilaterally symmetrical.
Thus, the correct answer is option B.
