答案是c，但我选的是a，谁能告诉为什么选c吗？

1）directive 作为名词，其后的that从句是同位语（that any chemical banned on medical grounds in the United States be prohibited from sale to other countries），解释说明directive,that 从句不能使用虚拟语气。

注：如果direct 作为动词，表示命令，其后宾语从句需用虚拟。

2）至于其他错误答案，在于prohibit词的用法不正确。

E选项错误的原因：
2 things

* if you have
a directive/order/command + that + noun + verb
then the verb must be in the COMMAND SUBJUNCTIVE.
so this would have to be
"...directive that any chemical banned in the United States on medical grounds be..."

* you don't use "X is prohibited from ..." unless X is a person.
the chemical is prohibited from being sold --> wrong
chemical companies are prohibited from selling the chemical --> correct

针对A选项：
学生问：I'm confused why the command subjunctive is not used in this case?

Ron回答：it can be used -- that's not the error.

perhaps the biggest problem in (a) is the misuse of "prohibit X from Y", which should only be used when X is a person and Y is a prohibited action.
