https://www.cisco.com/c/en/us/td/docs/security/firepower/640/configuration/guide/fpmc-config-guide-v64/When configuring Cisco FTD with integrated routing and bridging, a bridge group is created to connect multiple interfaces together to function as a single network segment. This allows for traffic to be passed between interfaces without the need for a router.
In this setup, a bridge group member interface is connected to the network segment and functions as the bridge group's primary interface. A routed interface is also configured with an IP address, allowing it to communicate with other networks.
To allow communication between the bridge group and the routed interface, the bridge group is configured with a subinterface. The subinterface is created on the routed interface and assigned to the same VLAN as the bridge group.
Therefore, the correct answer to the question is A. subinterface.
