This question seems to have no valid correct answer as the incoming SDP only offers 0 and 18 and not 8 so the outgoing SDP would match the available codecs in order of preference based on voice codec 1 which is 0 18. B is the closest available answer although the order of codec preference is incorrect.
The outgoing SDP will prefer PCMA (G.711alaw) first (RTP/AVP 8), followed by PCMU (G.711ulaw) (RTP/AVP 0), and finally G.729 (RTP/AVP 18), based on the codec preferences set in the voice-class codec 1 on both dial peers.
change my mind, based on Cisco: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/ios-xe/config/ios-xe-book/m_voi-negt-aud-code.html#reference_D708A3F6727C4E47BBE1C0B9B417BFA7
In it, this note: Codec preference in the voice class codec on the outgoing call leg is not followed when the same codecs are available in the respective incoming invite with SDP with different codec preference. Cube prioritizes and follows the incoming invite with SDP codec preference when compared to the voice class codec preference on the outgoing dial-peer leg. So should be B.
This should be B - it compares with the invite before sending to CUCM leaving G.711ulaw and G.729 remaining. For some reason the order is messed up but it seems like the best answer still.
