What does preserving highlights mean in a line drawing?

Leaving empty or light areas in illuminated parts

Preserving highlights is a tonal and line-control method used to show where light strikes a subject. The artist deliberately leaves selected areas blank or very lightly marked instead of covering them with dark hatching. The contrast between these light areas and the surrounding lines suggests shine, reflection, or a strong illuminated surface. Option A is correct because it describes protecting the lightest visual spaces. Options B and C would remove the contrast needed to communicate light, and D concerns the frame or outline rather than illumination. Highlights should be placed purposefully according to the imagined light source, not scattered randomly. Keeping them clean also helps the drawing retain clarity and a sense of form.
