I'm not sure about that. Shouldn't the device with the highest MAC address be elected as the root bridge in this scenario? This is confusing.

I'm not sure, but I think the rationale behind A) is that STP uses the Bridge ID, which is a combination of the bridge priority and MAC address to elect the root bridge.

I think option A is the correct answer. Without a configured root bridge priority, the device with the lowest MAC address will be elected as the root bridge.
