B. E has two problems, 1) but and nevertheless is redundant; 2) "a system" following "Sounds:" they don't match.

看来只有B了。

B的逻辑意思不对，they从逻辑上指代dolphins，但是dolohins can not produce a system. I prefer E than B, which is logically and grammatically right, although there is one wordy of but and nevertheless redundancy.

在网上找到这么一句

dolphins lack vocal cords, but they do use a complicated system of whistles, squeaks, moans, trills, and clicks.

虽然和题目不一样，但是大家也可以知道一下题目的方向。其实不用刻意追求哪个答案，万一那个真题被人记错了，岂不是耽误我等，呵呵。

晕一下，这次的搜索和原句更靠近了
