Which statement best describes profile of a surface?

Explanation:
The profile of a surface is about the geometry of the surface boundary—the contour that defines the surface in space. It specifies how that boundary is shaped, including its form (curvature, flatness) and, when needed, its orientation relative to datums. It’s not about where the surface sits relative to datums, its overall size, or the texture of the surface. So the best description is that it represents the shape of the surface boundary, including form and sometimes orientation.
