Wait, is this a trick question? What if the answer is actually /dev/null, and we're all just overthinking it?

Aha, /etc/securetty is the one! I remember learning about that in my Unix administration class. It's like the bouncer for the root user.

Haha, /etc/ioports? Really? That's where you configure your hardware ports, not your secure terminals. Nice try, though!

Hmm, I'm not sure about this one. Maybe /etc/services or /proc/interrupts? I always get those Unix config files mixed up.

Definitely /etc/securetty. That's the file where you can specify which terminals the root user can log in from. Easy peasy!
