Step-by-step explanation:
The term you're describing is related to architectural elements of buildings, more specifically, it refers to bay: a division of a building marked off by vertical or transverse supports, such as columns. Option 3: Bay is the correct answer. In architectural terminology, bay refers to the space between two columns or supports, often seen in the nave of a church. It is important not just in religious architecture but also in the design of other types of buildings.
In addition to bays, other related terms include aisle, which is the space within a church flanking the nave and separated from it by columns or arcade. A parapet is related to the exterior perimeter that extends above the roofline, while a pilaster is a decorative feature resembling a flattened column attached to a wall.
The Interior Design of Buildings
For instance, the interior is often divided into several aisles by rows of columns or piers. These structural elements support the roof and divvy up the interior space in a balanced way, which can be observed in the layout of church naves. The aesthetics can be further enhanced by using vivid color schemes and decorations such as stucco pinecones and volutes.
