window.
- Hide the HelpViewer control.
- Dock the HelpViewer control.
You create a main window as a base class.
What should you do next?

• A.Add the HelpViewer control to a DockPanel control at runtime.
  Inherit all other window classes in the application from the main window base class.
• B.Add the HelpViewer control to the window at runtime.
  Inherit all other window classes in the application from the main window base class.
• C.Add the HelpViewer control and a Frame control to a DockPanel control to the window at runtime.
  Create all other windows in the application as pages and host them in the Frame control.
• D.Add the HelpViewer control and a Frame control to a StackPanel control to the window at runtime.
  Create all other windows in the application as pages and host them in the Frame control.

You are designing a Windows Forms application that allows users to search a product catalog and place orders.
