CTRL+F6 switches to the next workbook window when multiple Excel workbooks are open. This is the standard keyboard shortcut in Excel for cycling through open workbook windows.

In Excel, CTRL+F9 minimizes the current workbook window to an icon at the bottom of the screen. This is a standard Excel shortcut that reduces the workbook window without closing it, allowing you to see other open windows.

Both SHIFT+F11 and ALT+SHIFT+F1 insert a new worksheet in Excel. These are two different keyboard shortcuts that perform the same function of adding a new sheet to the current workbook. Since both options (A and B) are correct, option C (A and B) is the right choice.
