Which statement about fog is more correct?
Answer and explanation
Correct answer: It is a dispersion of water droplets in gas, not a true solution
Fog consists of tiny liquid water droplets dispersed through the surrounding air. Because the droplets remain distinct particles instead of becoming molecularly dissolved, fog is a liquid-in-gas colloidal dispersion rather than a true solution. It is not a solid-in-solid mixture, salt water, or merely invisible water vapour. Hence option A gives the correct description.
