The correct answer is A. Click the application minimize button.
To exit PowerPoint, you can click the application minimize button, which is the small, downward-pointing arrow in the upper-right corner of the PowerPoint window. This will minimize the PowerPoint window to the taskbar. You can then click on the PowerPoint icon in the taskbar to reopen the window.
Option B is incorrect because clicking the document close button will close the current PowerPoint presentation, but it will not exit PowerPoint.
Option C is incorrect because double-clicking the application control menu icon will open a menu of options for PowerPoint. You can then click on the “Exit” option to close PowerPoint.
Option D is incorrect because double-clicking the document control menu icon will open a menu of options for the current PowerPoint presentation. You can then click on the “Close” option to close the presentation, but it will not exit PowerPoint.
