Which of the following is defined as being bounded on three or more sides?

A court is defined as a space that is bounded on three or more sides. It typically refers to an area that is enclosed or surrounded by building walls or structures on three sides, allowing for light and air to enter while also providing a defined space. This definition aligns with architectural terminology where "court" is used in both residential and commercial contexts.

In contrast, a yard typically refers to an open space, often found around a building, which may not necessarily be enclosed on three sides. A yard can be open to one or two sides, making it less restrictive in terms of boundary definition.

Therefore, the correct response is that a court is specifically defined as being bounded on three or more sides, which accurately reflects the nature of the term within the field of architecture and building design.
