If the primary root bridge experiences a power loss, which switch takes over?

Question:
If the primary root bridge experiences a power loss, which switch takes over?

• switch 0040.00.90C5
• switch 00E0.F90B.6BE3
• switch 0004.9A1A.C182
• switch 00E0.F726.3DC6

Explanation: The switches compare their Bridge ID with each other to find out who will be the root bridge. The root bridge is the bridge with the lowest bridge ID.

Bridge ID = Bridge Priority + MAC Address

In this question the bridge priority was not mentioned so we suppose they are the same. Therefore the switch with lowest MAC address will become the new root bridge.
