Just to clarify, angel, I think you mean that B is the least worst, and B (the correct answer) is the one you just don't want to pick even after looking at it again?
Assuming that, once again you should look to the text, starting at line 15:
The idea of self was, in a number of pre-contact Native American cultures, markedly inclusive: identity was not merely individual, but also relational to a society, a specific landscape, and the cosmos
(emphasis added)
The cosmos refers to the stars, the galaxy, the universe - all that stuff out there beyond the sky. That's the best support you will find for the idea that someone's name might include a reference to a constellation.
Another way to look at it is by recognizing that there is no support - none - for any of the other answer choices. Sometimes, what makes one answer the best answer is not that it is strong, but that the others are weak. There is at least that one reference to help answer B, but no such similar support in the text for any other choice. Stick to the text, and look for support for your contenders. The one with the most support (in this case, the only one with any support) is the best answer.
I hope that helps! Good luck!
