Correct Answer:
C. c) log file
Log file is where most operating systems write error information when a process fails.
A log file is a dedicated file designed to record system events, including errors. By storing error information in a log file, the operating system can provide a detailed record of the issue for later analysis, troubleshooting, and debugging. This helps system administrators and developers identify the root cause of problems and implement solutions.
Creating a new file for each error would be inefficient and impractical. Writing to another running process could interfere with its operation and potentially cause further issues.
