What relation can line have with form?

Line can suggest form by showing surface direction

A line can do more than mark an outer boundary. When it follows the direction of a surface, it can help the viewer imagine how that surface bends, turns, or extends in space. Curved lines across a rounded object, for example, can suggest its volume and three-dimensional form. These lines are often called surface or contour lines in art discussions. They guide the eye and provide information about the structure of the object.

Therefore, the correct choice is that a line can suggest form by showing surface direction. The line does not always hide form; it may explain it. Form is not made only by sound, since visual marks, light, shade, shape, and line can all help describe it. The final option is also incorrect because line has an important role in showing structure, movement, depth, and the way a surface is shaped.
