Correct Answer: Option 2 E & I

Species E and I both originated from species F. There are most likely more common shared characteristics (synapomorphies) between these two species than the other species given.

Species C originated from species H, while species D from G. Since they have different most recent ancestor, they are not as closely related as E & I. Thus, option 1 is incorrect. This is also the case of options 3.

Option 4 is also incorrect. Though species A is the remote ancestor of all the given species, there have been many diversion from the original characteristic before species F came to existence.
