Answer: C) prokayotes
Step-by-step explanation:
According to Lynn Margulis endosymbiotic theory, cell organelles of eukaryotic organisms, such as mitochondria and chloroplasts arise by the combination of two prokaryotes. An aerobic bacteria, were engulfed by anaerobic bacteria. They live together as symbiotic partners for mutual benefits. The aerobic bacteria take care of the toxic oxygen for the anaerobic bacteria, in return the anaerobic bacteria would ingested food and protected the aerobic bacteria. Thus, a eukaryotic cell with a double-membrane bound organelle is formed.
