OA D
Why not B???
Thanks!

I eliminated B based on the pronoun ambiguity - 'its' refers to the star, but it comes before the star in the sentence, making it look like 'its' refers to the red giant stage.

In other words, it makes it look like the change depends on the mass of the red giant stage.

A is also ambiguous with the pronoun 'it'; in C and E the modifier "after passing..." incorrectly modifies "a star's mass" or "The mass of a star" instead of modifying the star.

In D there is no pronoun ambiguity and the modifier correctly modifies "a star".
