D
Correct answer
Explanation
Menus are the only option that can recursively contain themselves - a menu can have sub-menus, creating nested hierarchical structures. Forms contain fields/controls but not other forms. Tables contain rows/cells but not other tables. Commands are executable actions, not containers. Inquiries are query definitions, not hierarchical. This recursive nesting capability is unique to menus in GUI systems.
