Explanation

To permanently resolve high CPU load caused by a runaway process, the process must be terminated. kill -9 6295 sends the SIGKILL signal to process ID 6295, forcibly stopping it and freeing the CPU resources it was consuming. Option A (renice) only changes process priority but leaves it running, which does not permanently fix the issue. Option B (pstree) is a diagnostic tool only. Option C (iostat) reports I/O statistics and does nothing to resolve CPU load. Only killing the offending process (D) permanently resolves the issue.
