The best way to protect a network from SMB attacks is to make sure routers filter out ports 137 to 139 and 445. Port 445 is specifically used by SMB2 and SMB3 protocols, which are commonly targeted by attackers. By blocking this port, you can prevent attackers from exploiting vulnerable SMB services on your network. Therefore, option C (445) is the correct choice.
