Refer to the exhibit. The Cisco UCS domain is operating in switching mode. A network administrator notices that no traffic is traversing the uplinks on Fabric Interconnect B （Path C）.    Which actions might be used to change this behavior？（）

• A、 Fix the port channel configuration between Fabric Interconnect B and Nexus 5548 B as the port channel IDs do not match.
• B、 Modify the bridge priority on the fabric interconnects so that one of the Nexus 5548s will always be the root bridge.
• C、 Modify the bridge priority on the Nexus 5548s so that one of them will always be the root bridge.
• D、 Modify the port priorities on the fabric interconnect uplinks （Paths B and C） so that they are a higher priority than ports Eth1/4 and Eth1/9 （Path D）.
• E、 This is an invalid configuration as Cisco UCS fabric interconnects cannot be directly connected.
