GMAT Sentence Correction (SC) | Re: Like any star of similar mass would do, once the Sun has

There is another issue in D, which does not seem to have been highlighted so far. It says:

once the hydrogen in the Sun’s core is exhausted

This does not tell us who exhausts the hydrogen in the Sun’s core. The original sentence says: once the Sun has exhausted the hydrogen in its store.

So, this is a big meaning issue with D.
