Solution
The correct option is B Mollusca Mollusks are invertebrates. They are also the largest marine phylum. They are found in various marine and freshwater habitats. They are basically divided into gastropods, cephalopods, and bivalves. The gastropods have a visceral mass or visceral hump inside their shells. It generally contains the digestive, reproductive, respiratory and excretory systems of the organism. The muscular foot of gastropods is an organ that facilitates movement.
