a
This cladogram does not show that organism X and organism Y are more closely related based on the similarities in their DNA.
b
This cladogram shows all of the organisms being closely related.
c
This cladogram incorrectly shows organism X and organism Z being more closely related.
d
This cladogram correctly shows that the three organisms share some DNA, but that X and Y are more closely related based on the similarities in their DNA.

Answer 1
