Explanation:
To block phone A from making long distance calls, phone A must belong to an incoming dial-peer which is not a member of the LD (Long Distance). In three incoming dial-peer (the three last dial-peers), there is only one dial-peer satisfies with this condition, that is the LocalLst dial-peer so the answer should be E.One tip to quickly recognizes which dial-peer is for outgoing dial-peer is that this type of dial-peer usually have only one member. In this question, the outgoing dial-peers are Em01, Local01, LD01, Intl01. Dial-peers which have more than one member are often incoming dial-peers.
