Shading with parallel lines is an example of which technique?

Correct answer: Hatching

The direct answer is D, hatching. Hatching is a drawing technique in which parallel lines are placed close together to suggest shade, form, or darker tone. Step by step: decide which area should look darker; draw repeated lines in the same general direction; keep them closer or press slightly more for stronger darkness; leave lines wider apart for a lighter area. Option D is correct because parallel-line shading is the basic meaning of hatching. Option A, stippling, makes tone with separate dots rather than lines. Option B, wash, uses diluted paint or ink spread in a fluid layer, not specifically parallel lines. Option C, hue, means the basic colour family, such as red, blue, or green; it is a colour property, not a line-shading method. Cross-hatching uses a second set of lines crossing the first, but ordinary hatching already fits the question. Memory cue: hatch means lines; cross-hatch means crossing lines.
