Explanation

The clutch has the role:

to progressively transmit the rotational movement from the engine to the gearbox when starting from standstill;
it couples and uncouples the engine from the transmission in order to be able to change the gears;
it protects the transmission from overload.

The clutch transmits the rotational movement from the engine to the gearbox. The movement can be transmitted:

100% when the clutch pedal is free (not pressed);
partially - when the pedal is around the middle position;
0% when the pedal is fully pressed.

Thus, you can start smoothly from standstill or drive very slowly to perform parking, U-turns etc.

The correct answer is: C
