1、应该是。
2、我是这样排除的：
A. the compliance date was subject to postponement according to the terms of the treaty
文中推不出推迟的信息。
B. one of the countries might not be required to make any changes or take any steps in order to comply with the treaty, whereas all the other countries are so required.
条款已经规定，大家要求遵守。
C. Each country might have a well-founded excuse, based on the provision, for its own lack of compliance.
由于on simultaneous action，和notify the six other countries when it had completed its action.因此，有些国家会利用借口，不参加某一次的或超过fixed day。
D. The treaty specified that the signal for one of the countries to initiate action was notification by the other countries that they had completed action
这不是可能，而是实际存在的。
E. There was ambiguity with respect to the date after which all actions contemplated in the treaty are to be complete.
没有ambiguity 。
