我觉得 e 把原句的主语变了。

如果说a 中修饰有歧义的话，我看b， c就没有歧义了，而且主语没有改变。

请问为什么选 e
a，b，c，怎么错了？？？

As many 牛牛 ever mentioned, the expression
A of B , which + singular verb...
is ambiguity.

which = A, B, or A of B ?

About 191,
B and C imply that
A derivative is cultivated in China...
That is illogical and distortion.
