  1. A.Water droplets can obscure the reflected image.
  2. B.Water droplets help to keep them clean.
  3. C.Water can cause a short-circuit in the electrically heated mirrors.
  4. D.Water droplets can make the reflected object appear closer than it really is.
Show answer & explanation

Correct answer: A. Water droplets can obscure the reflected image.

When driving in wet weather conditions, small water droplets can form on the glass of the exterior mirrors. This could make it more difficult to see the road behind and to the sides. Switch on the mirror demisters, if they are fitted. If necessary, stop and clear them.
