Answer 1

The correct answer is:

(c) Quantity governing

In petrol engines, quantity governing is the method used to control the engine's speed and power output. This is typically achieved by regulating the amount of fuel and air mixture entering the engine. By adjusting the throttle valve, the engine's power is controlled by varying the fuel-air mixture, making it a form of quantity governing.
