What is the main way to control both form and feeling through line?

Changing direction, weight, movement, and character according to subject

The governing concept is the dual structural and expressive role of line. Structurally, direction and weight can describe contours, planes, edges, and the apparent movement of a form. Expressively, fast, angular, broken, soft, or flowing marks can suggest energy, tension, calmness, sadness, or strength. Option A is correct because it combines the main controllable qualities and connects them to the subject. Option B creates accidental confusion rather than controlled expression. Option C may produce uniformity but cannot distinguish different forms or moods effectively. Option D removes an important visual element instead of controlling it. A skilled artist therefore changes line qualities deliberately so that the object’s construction and emotional character support each other.
