The correct answer is: C. Opens a shortcut menu listing everything you can do to the object.
When you right-click something in Excel, a shortcut menu will appear. This menu will list all of the actions that you can take with the selected object. For example, if you right-click a cell, the shortcut menu will include options to insert a new row or column, delete the cell, or format the cell.
The other options are incorrect. Option A is incorrect because right-clicking does not delete the object. Option B is incorrect because the right mouse button is not just for left-handed people. Option D is incorrect because right-clicking does not select the object.
