Selected Answer: D
D is correct. Since the Max Bitrate is only 40kbps, G722 (rtpmap:9) only goes down to 48kbps and G711 (rtpmap:0 ulaw/8 alaw) is 64kbps leaving only G729 (rtpmap:18).

Slushed is right. On this question you have a limitation of 40K for BW. G722 can use only 64k, 56K or 48K. So Answer is D
