What are the four options that are available to view open excel workbooks?

In Excel, you can view open workbooks using four main options: the View tab in the Ribbon, which offers different views like Normal, Page Layout, and Page Break Preview; the Switch Windows option under the View tab to toggle between open workbooks; the Taskbar, where each workbook appears as a separate icon; and the Ctrl + Tab keyboard shortcut to cycle through open workbooks. These methods provide flexibility in managing and navigating between multiple workbooks.
