The answer to this question depends on the topology of the network and the configuration of the switches. In a network running the Spanning Tree Protocol (STP), the switches elect a primary root bridge, which is the switch with the lowest Bridge ID. If the primary root bridge experiences a power loss, a new election will be held, and another switch will be elected as the root bridge.

In the absence of any further information about the topology and configuration of the network, it is impossible to determine which switch will take over as the root bridge in the event of a power loss. Therefore, none of the answer choices can be definitively identified as the correct answer to this question.

It is worth noting that in a well-designed network, the failure of the root bridge should not result in any significant disruption to network operations. The STP protocol is designed to detect changes in the network topology and reconfigure the network accordingly to maintain connectivity while preventing loops and broadcast storms.
