Which combination is most effective for showing depth in a scene using lines?

Converging directional lines and lighter lines in distant parts

The governing concept is linear perspective supported by variation in line weight. Converging edges, such as roads, rails, or building sides, guide the eye toward a vanishing region and make parallel distances appear to recede. Reduced pressure, lighter marks, and less emphasis in distant areas can reinforce atmospheric and spatial recession. Consequently, option A is the most effective combination. Uniformly thick lines in option B flatten the scene by giving near and far objects equal emphasis. Closed circles alone do not establish directional recession, and erasing every line removes the structure needed to communicate depth. The method works because direction and emphasis cooperate rather than operate separately.
