What information can be derived from the output?

A.
Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending
BPDUs with a superior root bridge parameter and no traffic is forwarded across the ports.
Once the inaccurate BPDUs have been stopped, the interfaces will need to be
administratively shut down, and brought back up, to resume normal operation.

B.
Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending
BPDUs with a superior root bridge parameter, but traffic is still forwarded across the ports.

C.
Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending
BPDUs with a superior root bridge parameter and no traffic is forwarded across the ports.
Once the inaccurate BPDUs have been stopped, the interfaces automatically recover and
resume normal operation.

D.
Interfaces FastEthernet3/1 and FastEthernet3/2 are candidates for becoming the STP
root port, but neither can realize that role until BPDUs with a superior root bridge parameter
are no longer received on at least one of the interfaces.
