According to the phylogenetic tree, which domains are more genetically related?

The first branch of the phylogenetic tree holds the species of the bacteria division. It contains thermotoga bacteria, green non-sulfur bacteria, cyanobacteria, gram-positive bacteria, and purple bacteria. The second branch of the phylogenetic tree holds species of the Eukarya. It contains diplomonads, microsporidia, trichomonads, flagellates, entamoeba, slime molds, ciliates, plants, animals, and fungi. The last branch of the phylogenetic tree starts at the beginning of Eukarya line and holds the species of the Archaea division. It contains Thermococcus, Pyrodictium, Thermoproteus, Methanobacterium, and extreme halophiles.

Answer: The correct answer is- Archaea and Eukarya.

As per the information about the (phylogenetic tree) given in the question,

the last branch of the phylogenetic tree begins with the line of Eukarya and then holds the species of the Archaea division, which includes those prokaryotic organisms that live in extremely harsh environmental conditions ( such as Methanobacterium, and extreme halophiles).  

As this last branch holds species of two domains ( from 3 domain system of classification that includes Bacteria, Archaea, and Eukarya) , which are Archaea and Eukarya as it begins with Eukarya and later on holds the species of Archaea.

Thus, it shows that Archaea and Eukarya are more genetically related.
