Final answer:
If the braking action has been reduced due to water or rain, the correct step to take is to apply light and steady pressure on the brake pedal until proper braking action has been restored.
Step-by-step explanation:
If the braking action has been reduced due to water or rain, the correct step to take is to apply light and steady pressure on the brake pedal until proper braking action has been restored. This is because applying sudden and hard pressure (option b) can cause the tires to lock-up and skid on the wet surface, making the situation worse. Light and rapid pumping of the brake pedal (option c) can also lead to loss of control as it can cause the wheels to momentarily lose contact with the road.
By applying light and steady pressure, the driver allows the brakes to gradually engage and create friction between the brake pads and the rotors, increasing the braking action. This allows the tires to maintain traction on the wet surface and helps in bring the vehicle to a stop safely.
