In Windows 10, which of the following keyboard shortcuts is used to display and hide the desktop?

Correct option is A

· Windows logo key + D: The Windows logo key + D shortcut is a quick way to toggle between showing the desktop and showing all open windows. When pressed, this shortcut minimizes all open windows, allowing you to view the desktop. Pressing it again restores all windows to their previous state. This is useful when you want to quickly access files or shortcuts on your desktop without closing or minimizing individual applications.
· Windows logo key + H: This shortcut is used to open the Share charm in some versions of Windows, allowing users to share content via email or other apps. It has no relation to showing or hiding the desktop.
· Windows logo key + C: This shortcut opens Cortana in listening mode if Cortana is enabled on your system. It is used for voice commands and not for desktop management.
· Windows logo key + G: This shortcut opens the Xbox Game Bar, which is used for gaming-related functions such as recording gameplay or taking screenshots. It is unrelated to desktop visibility.
