The answer is D because.

1) In gas turbine before of gases there must be a compressed air then and then only it's expand ended in turbine.

2) As the name sounds pneumatic drill. In pneumatic machines the working fluid is compressed air.

3) In superchargers there is also need of compressed air, because supercharger is also like a small gas turbine it has only one shaft on which compressor as well as turbine is fitted.

So the answer D is correct.
