What is done to make a light line?

Correct answer: Less pressure

A light line is produced when the pencil or drawing tool touches the paper gently. Pressure means the force used while drawing. When the pressure is small, less graphite or colour reaches the paper, so the mark appears pale and delicate. This is useful for outlines, first sketches, construction lines, and areas that should not look heavy. Therefore, the correct choice is B, less pressure. Very high pressure would make the line darker, thicker, or more strongly impressed in the paper. Tearing paper and drying colour do not control the darkness of a drawn line.

To solve this, connect the strength of the hand with the darkness of the mark. A soft touch generally gives a light line, while pressing harder gives a dark line. The exact darkness can also depend on the tool and paper, but among the given choices only less pressure directly produces the required result. Thus the supplied answer B is accurate and follows the basic principle of line control.
