Correct answer

  • BConsumiremos menos combustible.We will use less fuel.
Explanation

Engine braking is a technique for reducing your car's speed using the engine, without using the wheel brakes at any point. With this technique we will reduce fuel consumption, and the brake pads and discs of our car will also last longer. It is advisable to use this technique when driving at low or medium engine speed because, even if we shift down a gear, the vehicle can easily cope with the new engine speed.
