Solution

The correct option is D Looping and somersaulting
Hydra are generally sessile or sedentary, but they move for hunting. They move by bending over and attaching themselves to the substrate with the help of mouth and the tentacles, then releases the foot. This process is called as looping or somersaulting. By this process Hydra can move several inches a day.
Therefore, the correct answer is option C.
