An unlabeled hierarchical diagram of various astronomical bodies is shown below. The labels A, B, C, and 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.

H tricky one let me think and get back to u

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻

The answer is the third option extremely gradual
