You are creating a Windows application to manage customer relationships by using the .NET Framework 3.5. Users of the application access a form named FrmMain to view a list of contacts. When the user double-clicks the contact, the item details for the contact can be viewed on another form named FrmDetails.
You need to ensure that the application meets the following requirements:
* A user can compare the details of multiple customers simultaneously.
* A user can rearrange all the open instances of the FrmDetails forms as a cascade or a tile in the FrmMain form.

Create a new instance of the FrmDetails form for each contact. Call the ShowDialog method. Set the TopMost property of FrmMain to False.
B.
Create a new instance of the FrmDetails form for each contact. Call the Show method. Set the TopMost property of FrmMain to True.
C.
Set the IsMdiContainer property of the FrmMain form to True. Set the MdiParent property of the FrmDetails form to FrmMain.
