The get router info bgp summary output lists BGP neighbor status:
Prefix Reception: The " State/PfxRcd " column shows the number of prefixes received from the neighbor—neighbor 100.64.1.254 has " 1 " , confirming option A.
Received Message Count: Under " MsgRcvd " , 18 packets have been received from neighbor 100.64.1.254. This matches option C.
The second neighbor 100.64.2.254 is in " Active " state and has received/sent 0 packets, indicating that its TCP connection is NOT established, disproving option B.
There is no indication anywhere that the router is " still calculating " prefixes; " Active " just means no session is established, so option D is incorrect.
