D.

Explanation:
The root bridge of the spanning tree is the bridge with the smallest (lowest) bridge ID. Each bridge
has a configurable priority number and a MAC Address; the bridge ID contains both numbers
combined together – Bridge priority + MAC (32768.0200.0000.1111). The Bridge priority default is
32768 and can only be configured in multiples of 4096(Spanning tree uses the 12 bits extended
system ID). To compare two bridge IDs, the priority is compared first, as if looking at a real number
anything less than 32768…will become the target of being the root. If two bridges have equal
priority then the MAC addresses are compared; for example, if switches A
(MAC=0200.0000.1111) and B (MAC=0200.0000.2222) both have a priority of 32768 then switch
A will be selected as the root bridge.
In this case, 32768: 11-22-33-44-55-66 would be the bridge because it has a lower priority and
MAC address.
