Hierarchical structure formation in the universe is a process where small structures collapse under the force of gravity to merge and form larger structures. This continues through a series of mergers until the formation of galaxies, galaxy clusters, and superclusters. Therefore, option C, which states that small objects collapse then merge to form larger objects, is the correct choice.
