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.
The nurse should recognize this as Chvostek sign.
<h3>What is
Chvostek sign?</h3>
A clinical indication that someone may have low blood calcium levels is the Chvostek sign (a decreased serum calcium, called hypocalcemia). The aberrant twitching of muscles that are stimulated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII) is known as the Chvostek sign.
The facial muscles on the same side of the face will occasionally contract when the facial nerve is touched in front of the ear (called ipsilateral facial spasm). Frequently, the muscles that regulate the nose, lips, and brows will spasm.
