Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging the nuclei of atoms and not splitting them apart, as in nuclear reactors.

(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactors
(B) merging the nuclei of atoms instead of splitting them apart, like nuclear reactors
(C) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do
(D) and merges the nuclei of atoms but does not split them apart, as is done in unclear reactors
(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart
1 and连接merge和power并列的话 逻辑意思上不太对 前面说核子融合是。。。的动力 后面说使原子核结合并且不分开应该是起解释作用 所以这里用ing形式做伴随状语 另外按照原文本来的意思 改为平行结构似乎也不妥 如果用and平行连接的话 D中的结构就是sth that powers。。and merges。。but does not split。。。 这样可以吗？ 好象应该是sth that powers。。，merges。。but does not split。。。 ？

是不是D项和power并列就成了定语从句一部分，修饰the force。
如果是merging，那么句子就是Nuclear fusion is the force that-clause，插入语，as... 这样merging修饰的是Nuclear fusion。

D项的but does not是不是也有问题。not split them apart but merges the nuclei of atoms 才符合习惯啊
