Explanation

Port 3389 is the default port for RDP (Remote Desktop Protocol). Blocking a specific port is a function of a firewall, which inspects incoming and outgoing traffic and can deny traffic based on port numbers. MAC filtering (A) controls which devices can connect based on hardware addresses, not ports. Port triggering (C) dynamically opens ports based on outbound traffic patterns-it opens ports, not blocks them. Port forwarding (D) redirects inbound traffic on a port to an internal IP address-again, it opens/directs traffic rather than blocking it.
