Answer
Brief Explanations:
In a cladogram or phylogenetic tree where the y-axis represents time, species that reach the top line (labeled "Present") are extant (still 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 died out in the past. In contrast, species C, D, and E reach the "Present" line.
Answer:
A and B
