Which is the deepest conclusion about the expressive power of line?

Line is not only a boundary, but a language of feeling, movement, depth, and meaning

The governing concept is line as a fundamental element of visual language. A line can outline a shape, but its direction, thickness, speed, continuity, pressure, curvature, and placement also communicate ideas and sensations. Diagonals may suggest movement, broken marks may imply uncertainty, flowing curves may feel gentle, and changes in weight can describe depth or emphasis. Lines can therefore organise space and carry emotional, symbolic, and narrative meaning even when they do not represent a literal object. Option A is the deepest conclusion. Geometry, handwriting, and outlines are only limited applications, and denying any emotional connection ignores the expressive evidence found throughout drawing and design.
