老师 请问a 国家可以发行 本国货币债券或者 外国货币债券 因为国家可以印钱 本国货币债券的信用质量更好。a为什么不对呢？
没明白C的含义？这两个半句分别什么意思？

C is correct. The cret rating agencies assign ratings to bon anthe highest rating means highest cret anlowest cret risk. Cret rating agencies make a stinction between bon issuein sovereign's loccurrenanbon issuein foreign currency. Thus the loccurrenaffects the cret rating of the sovereign bon. The nationgovernment of a country will issue the loccurrenbon easier if the mestic saving base is stronger.这道题的意思能下吗？考点是什么？
