The correct sequence, based on scientific evidence, starts with the origin of cyanobacteria, which are among the earliest forms of life on Earth. Following this, the endosymbiotic theory suggests that mitochondria and chloroplasts originated from the engulfment of bacteria by early eukaryotic cells, leading to the origin of mitochondria first and then chloroplasts. Multicellular eukaryotes evolved after these organelles were established. Finally, fungal-plant symbioses represent a more recent evolutionary development, occurring after the establishment of multicellular eukaryotes.
