Explanation

After entering 'voice class codec 100' on a Cisco Unified Border Element (CUBE), you must define codec preferences using the 'codec preference' command. The correct sub-commands are 'codec preference 1 g711ulaw' to set G.711 mu-law as the first (most preferred) choice, and 'codec preference 2 g711alaw' to set G.711 a-law as the second preference. The preference number determines priority; lower numbers are preferred first during codec negotiation. Option C contains this exact correct sequence, while the other options contain incorrect codec names or preference numbering.
