What harm can the incorrect use of too many layers in cross-hatching cause?

Correct answer: Details can become muddy and heavy.

Correct answer: B. Cross-hatching builds value by placing sets of lines in different directions over one another. A few controlled layers can darken a passage and describe form, but too many dense or poorly planned layers can fill the spaces between details. The marks then merge into a dark, heavy patch, making edges and small features difficult to read; the drawing becomes muddy. A is the opposite of the usual result because added layers generally increase darkness. C is unrelated because graphite or ink line layering does not automatically change hue to blue. D is also opposite and visually illogical. Use layers gradually, vary pressure and direction carefully, and preserve important light areas.
