虽然我觉得ｓｉｐ在这里用进行时也没错～　　但ｃ与ｄ相比而言，c更易懂，更简洁。

but后是一个独立的句子，这个应该没有问题。

那么sipping引导的分词短语的逻辑主语应该就是主句主语，而A、B中的主句主语she或he都不能与their coffee一致。排除。

而A中主句是she noticed that

D、E中 改成了he seemd disoriented。排除。

剩下C

为什么不  were sipping?

as: while or when
I saw Peter as I was getting off the bus.
As time passed, things seemed to get worse.
Just as the two men were leaving, a message arrived.

但此处我觉得是用逻辑分析C 较好， 

(C) as they sipped their coffee the next morning, she noticed that he seemed disoriented

因为原义是：当他们在喝咖啡的时候，这个女的发现男的神智不清。 强调的是时间，不是喝咖啡的动作。

 (D) as they were sipping their coffee the next morning, he seemed, she noticed, disoriented

而D是， 当他们同时喝咖啡的一瞬间，男的好像神智不清了。  强调喝的时候，男的不行了。而女的发现是插入语，次之。
