The ACL is placed on the inbound Gigabit 0/1 interface of the router. Host 192.168.10.10cannot SSH to host 192.168.100.10 even though the flow is permitted.
Which action resolves the issue without opening full access to this router?

- B . Temporarily move the permit ip any any line to the beginning of the ACL to see if the flow works
- C . Temporarily remove the ACL from the interface to see if the flow works
- D . Run the show access-list FILTER command to view if the SSH entry has any hit statistic associated with it
