Which method is more effective for showing the weight of an object through line?

Giving dark and thick lines toward the lower side

The governing concept is line weight, meaning the visual strength created by thickness, darkness, and placement. Darker, thicker lines near the lower or supporting side of an object can make that area feel grounded and visually heavy, especially when they correspond to shadow or contact with the surface. Option A is therefore the most effective choice among the options. Dots alone do not establish a supporting structure, removing all lines eliminates the visual information, and only light wavy lines usually suggest delicacy or movement rather than solidity. Line weight should not be used mechanically: it must agree with the imagined light source, the object’s material, and its contact with the ground. Used thoughtfully, variation in thickness helps communicate both mass and stability.
