Species C is most likely to share synapomorphies with its sister species D. As the clade containing A and B is a sister to the clade containing C and D, it is less likely that A and B share synapomorphies with C. Species E is not related to any of the other species mentioned, so it is also unlikely to share synapomorphies with any of them.
