A user level process in Unix traps the signal sent on a Ctrl + C input and has a signal handling routine that saves appropriate files before terminating the process. When a Ctrl + C input is given to this process, what is the mode in which the signal handling routine executes?

Correct Answer: C — Kernel mode

Explanation:

The signal handling mechanism involves kernel intervention to context-switch and execute the trap routine.
