What can be shown by preserving an area of white paper?

Correct answer: Highlight

In pencil shading, the untouched white of the paper represents the strongest light falling on an object, called the highlight. Therefore option A is correct. A dark shadow requires accumulated graphite, a midtone requires partial shading, and reflected light is usually a weaker light area within the shadow side rather than the pure white highlight. Planning and preserving the highlight before applying graphite helps maintain the object’s form and direction of light.
