Answer:
B. introns.
Explanation:
Archaea is a unicellular organism which differ from eukaryotes.
Their cells lack organelles or other internal membrane-bound structures. Therefore, unlike eukaryotes, archaea does not have a nucleus separating their genetic material from the rest of the cell.
It has a piece of circular, double-stranded DNA located in an area of the cell called nucleotids. They do not reproduce sexually but through fission.
The genes of Archae-bacterial species do not have introns like the genes of Eukaryotic species do.
