Subject _____ is the mechanism of high temperature superconductivity.
[A] which continues to be intense debate.
[B] on which there continues to be intense debate
[C] on which it continues to be intense debate
[D] what continues to be intense debate
这题 选哪个？？为什么？？请翻译整句 谢谢
答案选B 为什么 清帮我分析一下并翻译整句 谢谢

A
debate是及物动词，字典中：
They debated the question openly.
他们公开辩论这个问题。
所以排除BC，因为不需on+which引导定语从句
另外，判断此句是定语从句，D是主语从句，不选。改成What subject continues to be intense debate……就可以了。
