Solution :
A is - "the common ancestor of all life ; the common ancestor of Bacteria and Archaea" (option D) because according to the above diagram( phylogenetic diagram) A is the ancestor of both Bacteria and group B and thus this shows that it is the last universal common ancestor of all life forms and its further classification gives rise to groups: B(archaea and eukarya) and bacteria.
B is - "the most recent species to evolve on earth; the last common ancestor of Archaea and Eukarya" (option B) because there are no subsequent ancestors after B in the diagram making it the last common ancestor of Archaea and Eukarya.
