Evolution leads to speciation, thereby species are related and they show evolutionary relationships.
A phylogenetic tree is a diagram that represents evolutionary relationships between species that share a common ancestor.
In conclusion, the organisms that are most closely related (based on the tree above described) are dinosaurs and crocodiles.
Thus, option "4" is correct.
