In which situation can an implied line be more effective than a drawn line?

When object directions guide the viewer’s eye without a drawn line

An implied line is not physically drawn, but the viewer perceives a directional path through the arrangement of objects, gestures, gazes, edges, or repeated forms. It can be more effective than a visible line when the artist wants to guide attention subtly without adding an obvious mark that might interrupt the image. For example, several figures looking toward one area can lead the eye there, or a sequence of objects can create a directional flow. Option A correctly describes this situation. Options B, C, and D remove the visual evidence needed to create an implied path, so they cannot explain effective guidance. The governing concept is that composition can direct the eye through relationships among forms, even when no literal line is present. Implied lines therefore support unity, movement, and visual connection.
