Answer is Wrong!
Answer is Right!
The correct answer is B. top.
A toolbar is a bar that contains a set of buttons or icons that can be used to perform common tasks. In a MDI form, the toolbar is displayed at the top of the form. This is because the toolbar is a common tool that is used by many users, and it is convenient to have it displayed at the top of the form where it is easy to access.
The other options are incorrect. Option A is incorrect because the toolbar is not displayed at the bottom of the form. Option C is incorrect because the toolbar is not displayed at the dim of the form. Option D is incorrect because the toolbar is not displayed at the frame of the form.
