Multiple choice general knowledge

Although fog consists of fine drops of water, we cannot see clearly through it because

  1. The light rays undergo total internal reflection in the

  2. Fine drops of water in fog polarize the light

  3. The drops scatter most of the light

  4. The fine drops are opaque to the light
