Which of the following ways of braking in a passenger car fitted with the ABS is the most effective?

In a car with ABS you brake most effectively by pressing the brake pedal quickly and hard - answer B. Pulse braking (A) is a technique for cars without ABS and here it only gets in the way, and pressing the clutch before the brake (C) takes away engine braking.

ABS itself detects the moment a wheel starts to lock and, a dozen or so times per second, reduces and restores the pressure in the system, so the wheels keep rolling all the time, and you keep steering control and can go around an obstacle. For the system to work, it must get full pressure on the pedal - so in an emergency you press it with all your strength and hold it until you stop, without being put off by the pulsing of the pedal. You press the clutch only at the end, so as not to stall the engine.
