Yes it is C but for future reference, both A and B are referring to solids, and D is referring to a gas, hope this is helpful later!
Answer: A) Mitochondria and chloroplasts are found in prokaryotes.
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.
<span>(Chloroplasts)
are found in unicellular organisms such as plants, and
(Mitochondria)
is found in almost all cells. (Chloroplasts convert light energy into sugar using photosynthesis,) and the (mitochondria converts sugar into ATP using cellular respiration.)
Both the mitochondria and chloroplast convert energy, have its own DNA, and are enclosed by two membranes.
