Why would hard identical lines be weak for showing soft fur texture?

They do not show the soft and irregular nature of fur

The governing concept is texture: marks should suggest how a surface feels and grows. Soft fur is made visually convincing by light, short, varied strokes that change in direction, length, density, and overlap according to the animal’s form. Hard identical lines repeat the same visual signal everywhere, so they look mechanical and rigid rather than soft, irregular, and flexible. Option A is correct because uniform harsh marks fail to communicate the tactile character of fur. Option B is an absolute and opposite claim. Option C is not automatic; highlights depend on light and value decisions, not merely repeated hard lines. Option D is also unsupported because depth requires form, overlap, value, or perspective cues. Texture is shown through purposeful variation, not mechanical sameness.
