Answer:
The correct answer is Archaea.
Step-by-step explanation:
The Archaea constitute a kingdom of single-celled microbes. These microorganisms are prokaryotes, which signifies that their cells are devoid of any cell core, that is, nucleus and other layer bound organelles. The Archaea are the species, which demonstrate the breaking points of life on the planet.
They were initially discovered and demonstrated in extraordinary circumstances, like earthy hot springs and aqueous vents. They were also found in a distinct scope of overwhelmingly acidic, saline, and anaerobic conditions.
