Solution
The correct option is B Starfish
Tube feet, which are found as part of the water vascular system, are the locomotory organs in starfish (an echinoderm). Jellyfish (a cnidarian) move through the water by radially expanding and contracting their bell-shaped bodies to push water behind them. Silverfish (an arthropod) have long antennae, and move in a wiggling motion that resembles the movement of a fish. In cuttlefish (a mollusc), the primary method of movement is by jet propulsion.
