Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.
Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting
Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and eventually ejects
As in the case of any star of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting
As any star of similar mass would, once the hydrogen in the Sun's core is exhausted it will expand into a red giant and will eventually eject
As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject
C, as+介宾结构，实质是as+一个省略了主谓只保留状语的句子，意为像……一样，不考虑and ejecting的错误，分析C的比较对象和省略是否正确：
As in the case of any star of similar mass, it will expand into a red giant once the hydrogen in the Sun's core is exhausted, 这里是将any star of similar mass和sun比较，in the case of any star里any star是主语，而主句里sun是地点修饰语，这样会导致被比较部分无法参照主句的格式做补全，说明该省略错误
结论：两个被比较部分在句子里充当相同的成分才可以做省略
