What effect can be created by drawing lines close together?

Dark tone

The governing concept is the relationship between line spacing and perceived tone. When many lines are placed close together, the white gaps between them become smaller, so the eye combines the marks into a denser and darker area. Therefore, option C is correct. This principle is used in hatching and cross-hatching to build shadows and model form without filling the area with solid colour. Lines placed far apart usually leave more visible paper and produce a lighter tone. Close spacing does not make the picture disappear, create paper shine, or automatically produce emptiness. The result can also depend on line thickness and pressure, but under comparable conditions, reducing the distance between lines increases visual density and generally makes the tone appear darker.
