Solution
The correct option is A Statocyst
An organ of equilibrium which is known as statocyst is present in molluscs. They are capsules which are filled with liquid and contains calcareous grains (statoliths) floating within. When the snail moves, the movement causes the statoliths float against the wall. The cilia detect the contact, which is then processed to the nervous system. This help to know the position and orientation in space. Thus, the correct answer is option A.
