Answer is A, as mentioned by Anki RR2 will not send an update to RR1 due to split horizon. Check the manual module 4 page 41.

Correct Answer is B: 2 Updates, One from peer eBGP e another from RR2, this last one will be set as invalid, but the "update message" was received and it should be counted.
