A Correct answer
Explanation

Ctrl+F9 minimizes the current workbook window in Excel, collapsing it to a taskbar button while keeping the file open. This is different from closing (Alt+F4 or Ctrl+F4) - minimized files can be restored by clicking the taskbar item. Maximize is typically done with the window controls, not a keyboard shortcut in Excel.
