292.Federal authorities involved in the investigation have found （the local witnesses are difficult to locate, reticent, and are） suspicious of strangers.

(A) the local witnesses are difficult to locate, reticent, and are
(B) local witnesses to be difficult to locate, reticent, and are
(C) that local witnesses are difficult to locate, reticent, and
(D) local witnesses are difficult to locate and reticent, and they are
(E) that local witnesses are difficult to locate and reticent, and they are

我选E
我感觉SUSPICIOUS应该是和DIFFICULT并列的，那么前面的LOCATE 和RETICENT就应该是一个小并列，当中应该也要有个AND，为此我至今迷惑不解。
请教NN

应该是C吧既然 是和difficult 并列 而且主语和系动词心痛不应该省略吗

其实这个应该是这样地 很难去找为一item ，reticent 为一个item 最后的作为一个item
而不能说很难沉默寡言 而是说他们经常沉默

如果locate和reticent并列，那么两个的词性应该相同；而这里一个是动词，一个是形容词。所以应该是difficult，reticent和suspicious并列。

应该选C，difficult，reticent和suspicious并列
