If every cross-hatching layer moves in the same direction which technique will it resemble?

Correct answer: Simple hatching

The governing concept is the definition of cross-hatching. Cross-hatching is made by overlapping sets of lines that run in different directions, whereas simple hatching uses repeated parallel or similarly oriented strokes. If every layer follows the same direction, the crossing relationship disappears and the result resembles ordinary simple hatching. Therefore option D is correct; stippling uses dots, while blending and smudging soften marks rather than create line layers.
