The block IP feature can be configured in two Security Profiles: Vulnerability Protection and Anti-spyware. The block IP feature allows the firewall to block traffic from a source IP address for a specified period of time after detecting a threat. This feature can help prevent further attacks from the same source and reduce the load on the firewall1. The block IP feature can be enabled in the following Security Profiles:

Vulnerability Protection: A Vulnerability Protection profile defines the actions that the firewall takes to protect against exploits and vulnerabilities in applications and protocols. You can configure a rule in the Vulnerability Protection profile to block IP connections for a specific threat or a group of threats2.

Anti-spyware: An Anti-spyware profile defines the actions that the firewall takes to protect against spyware and command-and-control (C2) traffic. You can configure a rule in the Anti-spyware profile to block IP addresses for a specific spyware or C2 signature.

Static IP and Dynamic IP and Port (DIPP) are two features that implement one-to-one translation of a source IP address while allowing the source port to change. Static IP translates a single source address to a specific public address, and allows the source port to change dynamically1. Dynamic IP and Port (DIPP) translates the source IP address or range to a single IP address, and uses the source port to differentiate between multiple source IPs that share the same translated address2. Both of these features provide a one-to-one translation of IP addresses, but do not restrict the source port. References:

Option B enables the required traffic by allowing SSL and web-browsing from UNTRUST to DMZ, denying SSH from UNTRUST to DMZ, allowing MYSQL from DMZ to SERVER, and allowing SSH from SERVER to DMZ. Option A allows SSH from UNTRUST to DMZ, which is not required. Option C denies all the required traffic. Option D denies all traffic from UNTRUST to TRUST, which is irrelevant to the question
