directive引导同位语从句是否该用虚拟语气呢？

题目：

One of Ronald Reagan's first acts as President was to rescind President Carter's directive that any chemical banned on medical grounds in the United States be prohibited from sale to other countries.

() that any chemical banned on medical grounds in the United States be prohibited from sale to other countries.

() that any chemical be prohibited from sale to other countries that was banned on medical grounds in the United States .

()  prohibiting the sale to other countries of any chemical banned on medical grounds in the United States .

() prohibiting that  any chemical banned on medical grounds in the United States is sold to other countries 

() that any chemical banned in the United States on medical grounds is prohibited from sale to other countries.

by说：directive作为名次，表示禁令，其后的that从句是同位语从句，解释说明directive，that 从句不能使用虚拟语气。所以ab排除。

可是我觉得这样分析是不对的。

ab不对在be prohibited from sale 。只能说be prohibited from selling.

固定用法：prohibit sth.;prohibit from doing ;be prohibit from dong sth.

哦，谢谢！
