Detailed Solution

Concept- Serial endosymbiosis theory is defined as the topological arrangement. An endosymbiont is a microbial cell that has evolved a long-term position within another microbial cell as a host. Endosymbiotic theory is a series of theories that see certain organelles in eukaryotic cells as descendants of endosymbionts.
According to the Serial Endosymbiotic Theory, the fusion of archaebacteria and eubacteria cells is how nucleated eukaryotic cells first appeared. The paradigm shift is that merging, rather than ramification, drives evolution. The acquisition of a mitochondrion by some progenitor of all eukaryotes is the most well-known—though by no means the only—example of serial endosymbiosis. The acquisition of a chloroplast occurred in some lineages (i.e., what would become algae).
Hence, the correct answer is the topological arrangement.
