I’m not so sure. What about A) output? Isn’t that for outgoing?

Agreed, B) input makes sense. SSH is incoming traffic.

I think it's B) input. It controls incoming connections.

I keep mixing up prerouting and input; I think prerouting is more for packets before routing decisions, so it might not be the right answer here.

I practiced a similar question where we had to filter access, and I believe the input chain was the correct choice for that scenario too.

I'm not entirely sure, but I remember something about the output chain being for outgoing traffic. That doesn't seem right for SSH access.

I think we should use the input chain for filtering SSH access since it's about incoming connections to the router.
