status bar is display at the . . . . . . . . of the mdi forms.

The correct answer is: A. bottom

The status bar is a bar that is displayed at the bottom of a window. It typically contains information about the current state of the window, such as the current date and time, the name of the file that is being edited, and the progress of a task that is currently being performed.

The other options are incorrect because:

• The top of the MDI form is typically reserved for the title bar.
• The dim is a property of a form that controls how the form is displayed when it is not active.
• The frame is the border that surrounds a form.
