What effect does changing the direction of a line have on expression in a drawing?

It can change movement, balance, and feeling

The governing concept is expressive direction in composition. The direction of a line guides the viewer’s eye and influences the visual forces felt in an image. Horizontal lines often suggest rest and stability, vertical lines can suggest height or firmness, and diagonal or sharply changing lines can suggest action, tension, or imbalance. Changing the direction can therefore alter movement, balance, and emotional feeling, making option B correct. It does not merely change the paper’s size, mix colours automatically, or always erase the drawing; options A, C, and D confuse line direction with unrelated physical actions. A skilled artist chooses direction deliberately so that the marks support the intended mood and arrangement.
