Final Answer:
If you must drive through deep puddles or flowing water, pumping the brakes may help keep them working. Option A is answer.
Step-by-step explanation:
Pumping the brakes is the correct action when driving through deep puddles or flowing water. Water can cause brakes to become less effective due to reduced friction between brake components. By pumping the brakes, you create additional pressure and friction, helping to dry out the brake pads and regain optimal braking performance. This technique prevents the brakes from becoming waterlogged and ensures a more reliable response when needed.
Applying the parking brake, turning off the engine, or shifting into neutral are not recommended actions for maintaining brake functionality in water. Pumping the brakes is a recognized method to address reduced brake effectiveness caused by water exposure. Option A is answer.
