In which situation is a lost edge effective?

Answer and explanation

Correct answer: When the object and background have nearly similar values

A lost edge is governed by the relationship between adjacent values. If the object and its background are nearly equal in tone, their boundary can visually merge, so the edge becomes soft or disappears in that area. Option A is therefore correct. Making every boundary darkest creates hard edges instead, geometric lines are irrelevant to the principle, and the absence of shadows is not required.
