Correct answer: D. Keep well back to allow following traffic to overtake.
You should always allow sufficient distance between your vehicle and the vehicle in front. This will enable you to stop safely (within the distance you can see clear). It will also give overtaking vehicles enough room to pull in safely to the left lane after they have passed you.
