This question appeared in some Mock GMAT
The time it takes for a star to change its brightness is directly related to the luminosity of it.
a. the luminosity of it
b. the luminosity of its brightness
c. the luminosity of a star
d. luminosity of it
e. its luminosity
The answer is E. Here is the explanation
The original version is grammatically correct, but the pronoun reference is vague. (To what does it refer?) (E) clarifies the pronoun reference by using the possessive its luminosity.
Isn't 'its' in option E also vague as it can refer to both "star" and "brightness"?

You're correct. (E) is the best choice purely for style reasons.

Pronoun ambiguity is a style issue, not a grammar issue.
Here's the list of priorities for SC:
1) grammar
2) meaning
3) style
In this question, (e) is clearly the best stylistic choice. Further, since the pronoun "its" is used previously in the sentence (and in that case can only refer to "star"), it's clear to what noun the second "its" refers.

Its refers to star not to brightness.
