What happens to tone when the density of lines increases?

Correct answer: Tone appears darker

Correct answer: A, the tone appears darker. Tone means the lightness or darkness seen in an area. In drawing, an artist can create tone without using paint by using closely spaced lines, a method often called hatching or cross-hatching. When the lines become denser, less white paper remains visible, so the eye reads the area as darker. If the lines are more widely spaced, the area usually looks lighter. Option B is wrong because the tone does not disappear; it becomes stronger or darker. Option C is unrelated because line density cannot change the physical length of paper. Option D is also unrelated because the name of a colour does not change through line spacing. Remember: more lines packed together produce a darker value; fewer, more widely spaced lines produce a lighter value.
