How is the relation between art and utility seen in architecture?

A building provides useful space along with beauty

The governing concept is the unity of function and aesthetic design in architecture. Architecture plans and constructs spaces for particular purposes, such as living, studying, working, worship, transport, or public gathering. At the same time, proportion, form, materials, colour, light, and ornament can make those spaces visually pleasing and meaningful. Option D is correct because it states both required aspects: a building offers useful space and may also possess beauty. Option A confuses visual and auditory experience, while B is false because planning is essential to safe and practical construction. Option C wrongly reduces architecture to writing. A building may be attractive but unusable, or useful but poorly designed; good architecture seeks a thoughtful relationship between use, structure, environment, and appearance.
