Why each option
A NAT pool is a designated group of public IP addresses that a router can use for Network Address Translation, often employed for dynamic NAT.
A NAT pool is explicitly defined as a range or group of public IP addresses that are available for a router to use when performing dynamic NAT translations for internal private IP addresses.
Dynamic NAT is a type of NAT operation, not a collection of addresses; it uses a pool of addresses to translate private IPs to public IPs on an as-needed basis.
Static NAT is a one-to-one, permanent mapping between a private IP and a public IP, which does not involve a pool of addresses for dynamic assignment.
One-way NAT is not a recognized or standard NAT term in networking.
