Answers
D.

cat /sys/block/loop0/events

Suggested answer: B

Explanation:

The grep -ir 'out of memory' /var/log command searches through log files in /var/log for any instances of 'out of memory' errors, which indicate that the oom-killer terminated processes due to insufficient memory. This is the quickest way to determine if the oom-killer caused the MySQL process to be killed.
