It's A. From the NPC course: The virbr0 Linux bridge carries management and storage communication between the CVM and AHV host. All other storage, host, and VM network traffic flows through the br0 OVS bridge. The AHV host, VMs, and physical interfaces use "ports" for connectivity to the bridge.

Bridge Bridges act as virtual switches to manage network traffic between physical and virtual network interfaces. The default AHV configuration includes an OVS bridge called br0 and a native Linux bridge called virbr0. The virbr0 Linux bridge carries management and storage communication between the CVM and AHV host. All other storage, host, and VM network traffic flows through the br0 OVS bridge. The AHV host, VMs, and physical interfaces use “ports” for connectivity to the bridge. https://www.nutanixbible.com/5a-book-of-ahv-architecture.html#:~:text=The%20virbr0%20Linux%20bridge%20carries,through%20the%20br0%20OVS%20bridge.
