How should Controlled Braking be performed in a vehicle?

Answer: C — Apply the brakes as hard as possible without locking the wheels

Controlled braking should be performed by applying the brakes as hard as possible without locking the wheels. This technique allows the vehicle to come to a stop quickly and effectively while maintaining control over the steering. Applying the brakes halfway or pumping the brakes quickly can lead to skidding and loss of control, while gradually pressing the brakes to a full stop may not allow for a timely and safe stop in emergency situations.
