RRB NTPC 2025 Graduate CBT 2 Question Paper PDF (10-Jul-2026) (Shift 1)
The correct answer is

Alt Key + F4 Function Key

In the Windows operating system, keyboard shortcuts using the Alt key combined with function keys perform quick window operations.

Pressing Alt + F4 while an application window is active instructs Windows to close that active application or window.

If Alt + F4 is pressed on the desktop with no application in focus, it opens the Shut Down dialog box instead.

The other combinations (Alt + F8, Alt + F1, Alt + F6) do not close the active application; F8 relates to boot options and F6 cycles through screen elements in some programs.

Hence, the correct combination is Alt Key + F4 Function Key.
