Answer:
Among the options you provided, the most common sectional view is the cross-section view.
A cross-section view is a two-dimensional representation that shows the internal structure of an object by slicing it along a specific plane. It provides a detailed view of the internal features, such as the shape, dimensions, and arrangement of components, that would not be visible in an outer or overhead view. Cross-section views are commonly used in engineering, architecture, and various fields to illustrate the internal details of objects, buildings, and systems.
