Why may the cast shadow of an object become softer farther from the light-blocking object?

Answer and explanation

Correct answer: Light spreads more around the edges

A cast shadow is formed when an object blocks light from reaching a surface. With ordinary extended light sources, rays can pass around the blocking object at slightly different angles. Farther from the object, this transition region becomes wider, so the boundary appears softer and less definite. Option A is correct. The effect is not caused by a change in object colour, paper thickness, or graphite erasing itself.
