Answer:
b.) pneumatic system
Explanation:
This system uses compressed air to transmit and control energy
In this exercise we have to identify which system uses air to work, so we have:
The pneumatic sytem.
Pneumatic systems are a series of interconnected components that use compressed air to perform movements in automated equipment.
In this way we can say that pneumatic systems are elements that transmit energy from the pressure of a gaseous fluid, such as compressed air. The operating principle is quite similar to that of the hydraulic system, using gaseous fluid instead of liquid fluid.
