Quizplus · Accepted Answer

Coffering is a method of creating a repetitive pattern of recessed square or rectangular panels in a ceiling. This technique helps to reduce the weight of a dome or arch by removing some of the material without weakening the structural integrity. At the same time, the recessed panels create a visual depth that enhances the illusion of recession in the ceiling, making the space feel larger than it actually is. Therefore, the best choice is D, which includes both of these benefits.
