The answer is false to your question.
The correct option to this question will be 'C' i.e., Gorilla Gorilla.
As the number of Differences of the amino acids representing for the beta-haemoglobin is less than other 5 species from humans, so we can say that Gorilla is closely related on the basis of molecular data given in the question. The beta Haemoglobin Gene is responsible for coding a protein which is called beta-globin. Each cell present in humans contains two genes of beta-globin.
The discovery of DNA in the mitochondria supported the endosymbiotic
theory. This is because it was established that, due to mutations in
this DNA there could be the development of new adaptations and species.
