I'm not even sure what this question is asking me for... please help asap!!! ( if you search this question on brainly in a new tab their is a picture of the diagram i couldn't figure out how to add it sorry)
An unlabeled hierarchical diagram of various astronomical bodies is shown below. The labels A, B, C, and D can be used to represent the Milky Way, universe, planets, clusters, and stars.



Part 1: Which four astronomical bodies would you choose to represent the four labels in the diagram?
Part 2: Justify your choice based on the hierarchical relationships in astronomical bodies.
