If the main subject must stand out but the background should remain attractive what is the most balanced use of line?

Correct answer: Clear line in main subject and light supporting line in background

Line is not only an outline; it can guide the viewer’s attention and establish a visual hierarchy. A clear or heavier line around the main subject gives it greater emphasis and makes it stand out. Lighter, thinner, or less assertive lines in the background can preserve interest without competing with the subject. This difference in line weight helps the viewer understand what should be noticed first and what should remain supporting information.

Choice A is therefore the most balanced approach. Using the same thick line everywhere would make every part equally forceful and weaken emphasis. Erasing the main outline would reduce clarity, while placing the heaviest line only in the background would draw attention away from the subject. The answer applies the principle of line hierarchy: stronger marks for focus and quieter marks for secondary areas.
