Answer: D - Static NAT performs a one-to-one mapping of an internal IP address to an external IP address.

Key Takeaway: Static NAT is a type of NAT in which a private IP address is mapped to a static public IP address. This allows an internal host, such as a Web server, to have an unregistered (private) IP address and still be reachable over the Internet. Dynamic NAT maps multiple internal IP addresses to a range of external IP addresses. Overloading NAT maps multiple internal IP addresses to one external IP address.
