What is an appropriate way to distinguish foreground grass from distant grass?

Correct answer: Use clear, varied marks in the foreground and show distant grass with simple tones and small groups

The governing concept is depth through detail, scale, and atmospheric perspective. Nearby grass is observed as larger and clearer, so varied individual marks can describe its blades and texture. Distant grass should be compressed into simpler tones and small grouped marks because separate blades are less visible. Giving equal detail everywhere flattens the scene, while making distant grass darker and sharper reverses normal depth cues. Option C is correct.
