b. the use of DNA as the information storage molecule
Explanation:
Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.

A dichotomous key is defined as a biological tool for identifying unknown organisms to a particular taxonomic level. It is constructed with many levels and series of couplets.
So, by observing the given dichotomous key, it is concluded that the correct answer is Option A- Organism X and Z have at least one observable trait in common in this dichotomous key.
