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.如题

B. merging the nuclei of atoms instead of splitting them apart,like unclear reactors

C. merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do

我想请问各位，C选项后半段的do 是与原文中的哪个词平行的？如果是与nuclear fusion is...平行，那是否do就该为is？

可merging the nuclei of atoms rather than splitting them apart是修饰主句里的force的啊~

那么nuclear reactors不是应该和主句的动词is 对称吗？实在不解~

恩~谢谢啦！
