(A) Air bladders (also known as swim bladders) are gas-filled organs that help fish maintain buoyancy. They are a characteristic feature of $Osteichthyes$ (bony fishes). $Chondrichthyes$ (cartilaginous fishes) lack air bladders,which is why they must swim constantly to avoid sinking. $Echinoderms$ are invertebrates and do not possess air bladders. Therefore,the correct option is $A$.
