Which statement is correct when visibility decreases greatly in fog?

Answer and explanation

Correct answer: The amount or density of tiny droplets may be high

Answer: A, the amount or density of tiny droplets may be high. Fog consists of very small water droplets suspended in air near the ground. Light passing through this layer is scattered in many directions by the droplets, so less direct light reaches the observer and distant objects become difficult to see. Option A is correct because a greater concentration of droplets usually causes stronger light scattering and poorer visibility. Option B is wrong because fog generally requires moist air near saturation, not completely dry air. Option C is wrong because fog contains suspended droplets and may also contain small particles that help droplets form; saying that no particles exist is incorrect. Option D is wrong because water vapour, condensation and weather are closely related. Fog is itself a weather phenomenon produced when moist air cools and condenses. Memory cue: more fog droplets mean more light scattering and less visibility.
