Best answer
Right choice is (a) Air motor

To explain I would say: A pneumatic motor (Air motor) is a motor which does mechanical work by expanding compressed air. Air motors generally convert the compressed air energy to mechanical work through either linear or rotary motion, and are preferred in highly explosive atmosphere.
