Answer: A) Mitochondria and chloroplasts are found in prokaryotes.

Step-by-step explanation:

Both mitochondria and chloroplasts contain their own DNA and ribosomes. The first endosymbiotic event occurred: The ancestral eukaryote consumed aerobic bacteria that evolved into mitochondria. In a second endosymbiotic event, the early eukaryote consumed photosynthetic bacteria that evolved into chloroplasts.
