OG，SC107，关于which用法的困惑。求解

echodancing

A：Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it.
C: A technique originally developed for detecting air pollutants, called proton-incluced X-ray emission , which can quickly analyze the chemical elements in almost any substance without destroying it.
两句里都有which，且都是跟在emission后面。解释里却说C中which错误指代了emission，而A中是正确的。很不理解。望高人指点，感激不尽。

这个应该是说which的跳跃修饰吧？我觉得逻辑上是说which去休息technique，

所以从位置角度来讲的话是A比较近。B的话太远了

我的理解是这样的
A. a technique called proton-induced X-ray emission, which
因为 a technique = X-ray emission，所以 which 可以使用
C: A technique originally developed for detecting air pollutants, called proton-incluced X-ray emission , which
因为 which既可以指代 a  technique, or detecting air pollutants, or X-ray emission，所以不可以被使用

不懂得是，是否在类似情况下，该规则都成立
比如： the great wall called the greatest building, which
这样是对的么？
再比如： the great wall is the biggest building, which
这样是对的么？
