Dear Admin, Fernando is right. Please correct answer.

/etc/crontab is a system-wide crontab. In its syntax must exist username. But in “E” answer there is no username. By this reason a can see only two correct answers — C and D. But Q require THREE answer… I’m confused…
Hi Alukardd,
It missed an username in option E. I fixed it.

Some genuinely interesting information, well written and broadly user genial.
