There is another question: "What is a limitation to consider when running a dynamic routing protocol on a Cisco FTD device in IRB mode? " - Only nonbridge interfaces are supported. So I think, it means Dynamic routing protocol is supported in IRB but with limitatiion.

people are believing too much in the chat-gpt

IRB is not the same as dynamic routing protocols. The first thing in cisco whitepaper regarding routed/transparent firewall and IRB is unsupported feautures, and the unsupported is etherchannel, Dynamic routing protocols.. so only A si the right one

IRB stands for Integrated Routing and Bridging and is a feature that enables bridging between two or more VLANs and routing between these VLANs as well. Therefore, the feature supported by IRB on Cisco FTD devices is: C. dynamic routing protocol IRB is a layer 3 feature and supports dynamic routing protocols such as OSPF, BGP, and RIP. It allows a device to route between VLANs while still maintaining layer 2 connectivity within the VLAN. Redundant interfaces, high-availability clusters, and EtherChannel interfaces are not directly related to IRB.

IRB (Integrated Routing and Bridging) is a feature that allows a router to perform both routing and bridging functions on the same interface. On Cisco FTD (Firepower Threat Defense) devices, IRB is supported, and it allows the device to perform layer 2 bridging and layer 3 routing simultaneously. With IRB, the FTD device can bridge traffic between interfaces on the same VLAN or subnet while also routing traffic between different VLANs or subnets. This is useful in scenarios where both bridging and routing are required, such as in a firewall deployment where the FTD device needs to perform both functions to enforce security policies.

A is correct. https://www.cisco.com/c/en/us/td/docs/security/firepower/640/configuration/guide/fpmc-config-guide-v64/transparent_or_routed_firewall_mode_for_firepower_threat_defense.html
