Answer options

Correct answer: B

Explanation

The correct answer is B, SIGINT, which is specifically designed to interrupt a running process when CTRL+C is pressed. SIGTERM (A) is a termination signal that can be sent to gracefully stop a process, while SIGSTOP (C) temporarily halts a process without allowing it to exit, and SIGKILL (D) forcefully terminates a process without cleanup.
