The correct answer for this question is B.
Explanation: To configure Cisco Unified Border Element to support up to five concurrent outbound calls across an Ethernet link with a bandwidth of 160 kb, we need to limit the number of calls to 5 using the "max-conn 5" command. We also need to specify the destination pattern using the "destination-pattern" command.
We can configure the dial-peer using the following set of commands:
dial-peer voice 1 voip translation-profile outgoing Strip9 max-conn 5 destination-pattern 91[2-9]..[2-9]$ session protocol sipv2 session target ipv4:142.45.10.1 dtmf-relay rtp-nte sip-notify sip-kpml codec ilbc mode 20
The "codec" command specifies the codec to be used for the calls. In this case, we have chosen "ilbc" with "mode 20" to ensure voice quality is not compromised.
Option A is incorrect because it does not specify the codec to be used for the calls.
Option C is incorrect because "aacld" is not a valid codec for voice calls.
Option D is incorrect because "mp4a-latm" is not a valid codec for voice calls.
