Question

Explanation:

The universe is hierarchically organized with smaller structures like planetary systems within galaxies, galaxies within galaxy - groups, and galaxy - groups within superclusters, all within the universe. The correct model should show this nested, hierarchical relationship.

Answer:

The bottom - most model (the one with concentric circles where the universe is the outermost circle, followed by supercluster, galaxy group, galaxy, and planetary system inwards) best represents the organization of the universe.
