How can line make the viewer’s eye move slowly or fast?

Soft wavy lines give slow movement and sharp diagonal lines give fast movement

The governing concept is visual rhythm and the directional movement created by line. Smooth, gently curving, widely spaced lines usually invite the eye to travel gradually because their changes are soft and continuous. Sharp diagonals, abrupt turns, repeated marks, and strong directional contrasts can make the eye jump or move rapidly across the image. Option A is correct because it connects line character with the pace of viewing, while recognising that the effect depends on arrangement and context. Option B is false because line qualities differ. Option C ignores a major guiding function of line. Option D is too narrow: colour can influence attention, but it is not the only device that controls eye movement. Spacing, rhythm, direction, contrast, and line weight also matter.
