D) it is located in the center of the solar system

Answer 1

The characteristic the sun has to keep the planets in orbit is A) Mass

Answer 2

A) Its mass

I think this is the answer because if another planet had a bigger mass the other planets and the sun itself would orbit it. I am not sure though this is my best guess.
