What can be done to make the title prominent in a poster?

Correct answer: Use large letters and contrasting colour

The governing concept is visual hierarchy in poster design. A title should be noticed quickly, so large, legible lettering and a colour that contrasts with its background give it emphasis. A clear position and adequate spacing can strengthen this effect. Option A is therefore correct. Very small lettering, hiding the title, or removing all colour reduces attention and weakens communication rather than making the title prominent.
