Though water is transparent to visible light, it is not possible to see distant objects in fog which consists of fine drops of water. This is so because :

afine drops of water are opaque to visible light
bmost of the light is scattered to create apparent opacity✓ Correct
clight rays suffer total internal reflection and are unable to reach the observer’s eyes
dMore than one of the above
eNone of the above

Explanation

(355) Distant objects cannot be seen through fog composed of fine water droplets because the fog droplets scatter light. As light passes through the fog, the tiny droplets scatter it, due to which the contrast of distant objects decreases and an opaque haziness is produced.
