In which condition will irregularity of line indicate intentional texture?

When bark, stone, or rough surface is to be shown

Irregularity becomes meaningful when it is controlled and related to the surface being represented. Bark may require broken, ridged and uneven marks; stone may need varied edges and scattered cracks; another rough material may call for changes in direction, spacing and pressure. Such variation gives the viewer a visual and tactile impression rather than looking like accidental carelessness. Option A is correct because the irregular marks serve the purpose of describing a rough surface. B calls for precision and regularity, C contradicts the use of visible line, and D explicitly removes the need for surface information. Intentional texture should still be observed and organized, not randomly added everywhere.
