Answer 1

Answer;

Molluscs

Explanation;

• Molluscs have a body plan with three main parts: a visceral mass, a mantle, and a foot.
• Mantle is a soft extension of the body wall in certain invertebrates, for example, Brachiopods and molluscs, which usually secretes a shell, thin body wall of tunicates.
• The foot helps molluscs to move and in gastropods it make mucus that the animal slides along.
• Visceral mass includes the gills, guts, and other organs in the center of an mollusk's body
