Answer
Brief Explanations:
In a cladogram or phylogenetic tree where the vertical axis represents time, the tips of the branches indicate the point in time when a lineage ends. Species that reach the line labeled "Present" are extant (currently living). Species whose branches terminate before reaching the "Present" line are considered extinct. In the provided diagram, the branches for species A and B end significantly below the "Present" line, indicating they did not survive to the current time. In contrast, species C, D, and E have branches that extend all the way to the "Present" level.
Answer:
A and B
