You cannot get the friend's list of your friend b, until you login with that b's credentials. Else you'll get OAuthException, which means you are not authorised or need a accesstoken / session of that particular user. Let me know why you need this maybe I can help.

Via the graph API this would be:

http://graph.facebook.com/<user_id_for_b>/friends
