What is a subset of an object's geometry, where sub-objects include vertices, edges, faces, polygons, and elements?

• A. Sub-object
• B. Transform
• C. Vertex
• D. Viewport

Answer: (A)

In 3D modeling, a subset of an object's geometry that includes vertices, edges, faces, polygons, and elements is called a sub-object. This concept lets you edit only a specific part of the model—for example, moving individual vertices to reshape a corner, adjusting edges to redefine a corner loop, or editing faces and polygons to modify surface topology. You can also work with elements to treat multiple polygons as a single unit for operations like extrude or detach. The other terms don’t fit because a vertex is just one type of sub-object, not the whole set; a transform is the action of moving or scaling the entire object, not a subset of its geometry; and a viewport is simply the window in which you view the scene.
