Which of the following options describes the role of the C-switch at 95%?

The C-switch at 95% plays a crucial role in the operation of aircraft systems, specifically regarding engine ignition and load management. When the C-switch is activated, it arms the load control circuits, which is essential for managing the electrical and operational demands of the engine. Additionally, it turns on the ignition system, ensuring that the engine is prepared to start and operate efficiently. This dual function of arming the load control circuits and activating ignition is vital for successful engine start procedures and overall aircraft operation.

In this context, understanding the specific function of the C-switch at 95% reinforces the importance of precise timing and system management in aviation mechanics, making option C the correct choice.
