Ah, the old 'Resource temporarily unavailable' error. Classic! I'd go with option C, as it's the most straightforward way to open up the firewall for SSH traffic.

This is a tricky one! I'm going to go with option C as well. It's always a good idea to double-check the firewall settings when troubleshooting remote connection issues.

I think option C is the way to go. Adding the SSH service to the firewall's public zone should resolve the issue. The other options don't seem quite right.

Hmm, it seems like the issue is with the firewall. The error message indicates that the remote SSH connection is being blocked, so we need to open up the firewall for SSH traffic.
