The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. Symbiosis is an interaction between two organisms of different species, and <u>endo</u>symbiosis is a type of symbiosis in which one organism lives <u>inside </u>the other one. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria, which specialized into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts, like bacteria, have their own circular DNA. They also have their own transcriptional and translational machinery.

Answer:
The correct answer would be option D.
I statement would not be a valid response as it is the fact on which the conclusion was made.
On the conclusion provided, one should ask about the cell type used in the study and the amount of chemicals those cells were exposed to.
Different types of cells may response in different manner against a particular chemical. For example, stem cell would response in different manner whereas differentiated cell would response in different manner.
Similarly, the amount or concentration of chemical plays important role in any reaction or cellular response. For example, the affinity of haemoglobin is high towards oxygen in alveoli whereas it is high towards carbon dioxide in body cell.
So, the correct answer would be option D.
