The correct answer is B: function x() { info=$(ping -c 1 $1 | awk -F "/" 'END {print $5}'); echo "$1 | $info" }. The ping command is used to measure network latency. The function provided uses ping -c 1 to ping the target once and extracts the average round-trip time using awk. This is a simple and effective way to monitor network latency during a scan or other network activity.
