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.
Option Elimination -
(A) 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 - Usage of "like" to compare actions is wrong.
(B) 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 - The star is compared with "hydrogen." Moreover, does "it" refer to "the hydrogen"? There is no "sun". It is possessive, acting as an adjective and not a noun. Wrong.
(C) 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 - same issue of "it" referring back to "the hydrogen"? Wrong. Moreover, "and" demands strict parallelism. We have a clause "it will expand into a red giant," before "and" and a phrase "ejecting ...blah blah.." after "and." Not parallel.
(D) 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 - "it" again referring back to "the hydrogen."
(E) 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 - ok.
