If an artist draws the main subject with light lines and background with dark lines, what may happen?

The viewer's attention may move toward the background

The governing concept is emphasis through line weight. Darker, thicker, or more strongly contrasted lines generally attract the eye because they carry greater visual force. If the background is drawn with heavy dark marks while the main subject is treated with faint lines, the background may become the strongest competing area. Therefore option A is correct: attention may shift away from the intended subject toward the background. Option B is not guaranteed and usually conflicts with the stated emphasis. Option C is impossible because line darkness does not erase a background, while option D is false because line weight is an important tool for directing attention. Artists normally reserve stronger emphasis for the focal subject and reduce it elsewhere.
