If lines gradually increase pressure from top to bottom in a composition, what meaning can be created?

A feeling of lightness above and weight below

The governing concept is pressure gradation, which changes line value and visual weight. A light touch at the top produces a softer, less forceful mark, while progressively heavier pressure toward the bottom produces darker and stronger marks. The eye can read this transition as a movement from delicacy to weight, elevation to grounding, or lightness to heaviness. Option A is correct because it describes the visual effect created by that gradual change. Option B would require pressure to remain similar in all areas. Option C is impossible because pressure changes the appearance of a line but does not make it vanish automatically. Option D concerns colour processes, not graphite or drawn-line pressure. The effect depends on controlled, continuous variation rather than an abrupt jump.
