Explanation

Exception handling is the process of detecting a runtime error or unexpected condition and responding to it gracefully to keep the program functional. Option C - 'If program module crashes, then restart program module' - is a textbook example: it detects a failure event (module crash) and takes a corrective action (restart the module) to recover. Option A describes process management (killing a duplicate instance). Option B describes input validation with a restart response, not true exception handling. Option D describes input sanitization to prevent buffer overflows - also input validation, not exception handling.
