Which exception is raised when a user interrupts the program by hitting Ctrl+C?

• A. InterruptException
• B. KeyboardInterrupt
• C. SystemExit
• D. UserInterrupt

Answer: (B)

When a user interrupts a Python program by pressing Ctrl+C, the program raises a KeyboardInterrupt exception. This specific exception is built into Python and is designed to handle interruptions triggered by a user. It allows a program to catch the event and respond appropriately, such as by performing cleanup operations or notifying the user. The other options do not correspond to the behavior triggered by Ctrl+C. InterruptException and UserInterrupt are not standard exceptions in Python, and SystemExit is raised when the interpreter is asked to exit, such as when using the exit() function or when the program finishes execution. Thus, KeyboardInterrupt is the correct and most recognized exception associated with user-initiated interruptions of a running program.
