katrin2010 [14]

Answer:

The correct answer is - Archaea.

Explanation:

Archaea is one of the three domains of life other than bacteria and eukarya. Archaea are prokaryotic organisms that are unicellular and present in very extreme conditions like salt environments or extreme heat.

Archaea used to be placed with bacteria but due to some closeness with the characteristic of eukarya as well as bacteria, it is placed as a separate domain. It lacks nuclei and has a cell wall in its cell.
