B Correct answer
Explanation

Cron's minimum granularity is 1 minute. The crontab syntax supports minute-level scheduling (*/1 for every minute), but there is no syntax for second-level execution. To run every second, you would need to use a different mechanism like a systemd timer, a loop script, or the 'sleep' command within a cron job running every minute.
