In which situation will the edge of a cast shadow be relatively softer?

Answer and explanation

Correct answer: When the shadow-casting object is farther from the surface

The governing concept is penumbra and shadow-edge softness. When the object is farther from the receiving surface, light from an extended source can spread around the object before reaching that surface, producing a wider, softer edge. Therefore option C is correct. Contact usually creates a sharper core edge, a very small source tends to sharpen shadows, and paper smoothness does not determine the optical softness of the cast shadow.
