As litigation grows more complex, the need that experts explain technical issues becomes more apparent.

(A) that experts explain technical issues becomes

(B) for experts to explain technical issues became

(C) for experts to explain technical issues becomes

(D) that technical issues be explained by experts became（C）

(E) that there be explanations of technical issues by experts has become

C我没意见，但A为什么不好，我觉得同位语从句对need做解释说明不好吗？

还是need for sb to do 是固定用法，没有the need 后面跟同位语从句的？

多谢NN能帮我看看～～

这里是讲需要什么，need for 目标明确；

不是讲什么样的需要， need + that 定语从句。不是语法错误，而是表达不清晰。
