Answer

Brief Explanations:

Compressed air is used to keep the valves from falling into the engine when replacing valve - stem seals on an assembled engine. It creates pressure to hold the valve in place. A magnetic pick - up tool is for retrieving small metal parts, a pocket screwdriver is a general hand tool, and a valve spring compressor is for compressing valve springs to remove or install them, not for preventing valve fall.

Answer:

C. Compressed air
