Answer:

A jackhammer.

Step-by-step explanation:

A jackhammer is a pneumatic device that was invented by William Mcreavy. Later, Mcreavy sold the patent of jackhammer to Charles Brady King. The tool is a combination of chisel and hammer. The tool is powered by compressed air to tighten or loosen an object. By using pressurized air, jackhammers help workers to drill and lossen an object.

Therefore, option A is correct.
