What minimum display is required for Windows Vista?

  1. DX8.0

  2. DX9.0

  3. DX10

  4. DX11

The correct answer is: DX9.0

Windows Vista requires a minimum display of DX9.0, which is the DirectX 9.0 graphics card with WDDM 1.0 or higher driver. This is necessary for the operating system to run smoothly and support advanced graphical features. While the other options, DX8.0, DX10, and DX11, are also DirectX versions, they do not meet the minimum requirement for Windows Vista and may result in compatibility and performance issues. Therefore, the answer B is correct.
