Answer:
The third option is the correct answer.
Step-by-step explanation:
As you may already know, a cladogram is a diagram capable of representing the evolution of living beings, through their ancestry and genetic similarities.
In a cladogram, the main line is the root and represents the common ancestor among all living beings that will be added throughout the cladogram. The adjacent lines, the main line are the branches and represent the groups of living beings represented. Each point between the lines, are the nodes and represent cladogenetic events.
As you can see in the cladogram shown in the question above, species C and D come from the same branch, which means that these species are more genetically close and that they have many similarities in their genomes. However, species B and C or D and E, despite having the same ancestor in common, come from different branches, which means that they are less genetically similar.
