If a poster title is clear from a distance but has uneven edges up close what correction is needed?

Correct answer: Refine the edges with a small brush after drying

The governing concept is finishing precision in painted lettering. Since the title is already readable at a distance, its size and contrast are adequate; the remaining defect is inaccurate edge control. Option D is correct because a small brush used after the paint dries can clean projections and regularise contours without disturbing the whole design. Enlarging, changing the background, or reducing contrast would not repair the uneven edges.
