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.
