请问outstanding 和 distinguished有什么区别

军队职称英语考试中有这样一道题目，让我很不解：
He will probably be awarded a Nobel Prize for his______achievements in chemistry.(2002 A类试卷)
A. outstanding B.distinguished
C.impressive D.substantial

大家可以选选试试，这种题目我觉得出的很没有意义。或许是我对英语词义没有细节的感知吧，求教大家啦，谢谢关注。
对啦，正确答案是outstanding，但是我本人实在是不明白。看来大家也不太清楚。
