Which keys can be pressed quit without saving in DOS

Solution (By Examveda Team)

In Disk Operating System (DOS), the key combination that can be pressed to quit without saving is Ctrl + C. This key combination sends a termination signal to the running program or command, allowing you to exit without saving changes or stopping the current operation.

Option A, "Ctrl + A," does not typically have a special meaning in DOS and is not used for quitting without saving.
Option B, "Ctrl + B," and Option D, "Ctrl + D," also do not have specific meanings for quitting without saving in DOS.

Therefore, the correct answer is Option C: Ctrl + C.
