Question

how do you close a file? select close from the file menu. click on the x at the top right of the screen. click on the close icon on the desktop. select close from the all programs submenu.

Explanation:

Selecting Close from the File menu and clicking the X at the top - right of the screen are common ways to close a file. Clicking a close icon on the desktop is not a standard way to close a file (it's more for shortcuts). Selecting Close from the All Programs sub - menu is incorrect as it's not related to closing an open file.

Answer:

Select Close from the File menu.
Click on the X at the top right of the screen.
