D is correct
C is wrong because this option makes the sentence sound like the discovery, not the star, was observed by Jocelyn. It's a modifier issue.

I think that tne issue with C is about the use of the past perfect. The past perfect refers to an event that is anterior to a past event. In the sentence, there is no post event to the discovery that is mentionned and that justifies the use of past perfect
