How should distant mountains be treated in atmospheric perspective?

Correct answer: Lighter, lower in contrast, and less detailed

The governing concept is atmospheric perspective. As distance increases, air and atmospheric haze reduce apparent contrast, edge sharpness, and visible detail; distant forms therefore appear lighter, softer, and less distinct than nearby forms. Foreground mountains or objects can use stronger darks and clearer marks, so option A reverses the depth cue. Thick outlines and equal sharpness would flatten the landscape. Option B is correct.
