大全58仍有一个点不明白啊

      Adult survivors of child abuse traditionally have had little or no chance that they could get their symptoms recognized and treated.

(A) that they could get their symptoms recognized and treated

(B) to recognize and treat their symptoms

(C) of getting their symptoms recognized and treated

(D) of recognizing and treating symptoms（C）

(E) of getting his or her symptoms recognized and treated

不是绝对不可以，只不过，要如何要求所有的survivors具备自我治疗的能力呢？还是C比较合理吧。

今天刚好看到这一题：

我觉得如果答案C改为 to get their symptoms recognized and treated更好一些。

白勇语法里边说下面的名词要求动词不定式做定语way, ability, power, tendency, capacity, reason, chance, time, method, attempt, opportunity, thing, work, property

但有人说薄冰语法里边说，chance后边接of doing, to do都可以

所以比较下来C是最好的答案了
