What is the real reason for low visibility in fog?

Answer and explanation

Correct answer: Tiny droplets scatter light

The correct answer is A, because tiny fog droplets scatter light. Fog consists of a large number of very small liquid-water droplets suspended close to the ground. When light from a vehicle, lamp, or distant object meets these droplets, it is scattered in many directions. Less light travels directly from the object to the observer, so outlines become blurred and distant objects are difficult to see. B is wrong because fog does not remove oxygen from the atmosphere; the main issue is optical scattering. C is wrong because the air does not literally turn black. D is wrong because the ground does not suddenly rise when fog forms. The practical result is reduced contrast and a shorter visible distance. Memory cue: “fog blocks clear sight by scattering light, not by removing air.”
