Solution

The correct option is B Aprasia

The phylogenetic tree shows the progress of time from left to right. The most recently diverged groups from a common point are shown farthest to the right on the diagram. The genera Pletholax is shown to be branched from a common point of genus Aprasia and Ophidiocephalus more recently than any other genus. Thus, the correct answer is option B.
