You create Microsoft Windows-based applications. You participate in the planning phase of an incident tracking tool for technical support analysts.

The incident tracking tool must meet the following requirements:

Technical support analysts must open multiple incidents simultaneously.
The application can run only one instance at a time.
Users must be able to adjust the order and layout of the incident screens.

You need to design an application user interface that meets these requirements with the minimum amount of code. Which action should you perform?

A.
Create a Multiple Document Interface (MDI) application with a menu strip. Utilize the
MdiWindowListItem property of the menu strip to automatically merge MDI child forms to the Window list.

B.
Create a Single Document Interface application that launches multiple forms. Write code to enable the user to toggle between the active forms.

C.
Create a Multiple Document Interface application with a menu strip. Write code to add child Windows to the menu strip to add MDI child forms to the Window list.

D.
Create a Single Document Interface application. Create a custom-dockable control that can display each support incident.
