What helps improve proportion in line drawing?

Correct answer: Guiding construction lines

Correct answer: A, guiding construction lines. Proportion means the size relationship between different parts of a drawing—for example, the width of an object compared with its height, or the size of one part compared with the whole. Before drawing dark final outlines, an artist can lightly mark a central axis, outer limits, basic shapes, and points where important parts begin or end. These temporary lines help compare distances and keep the drawing organised. A is correct because light construction lines provide a framework and can be corrected easily. B is incorrect because naming a colour does not measure size or distance. C is incorrect because frame decoration surrounds the picture and does not establish the object’s internal proportions. D is incorrect because smell has no role in visual measurement. Memory cue: first build lightly, compare parts, and finish firmly; do not confuse construction lines with the final outline.
