Correct answer is kingdom Monera. 

Archaebacteria are known to be the oldest living organisms on earth. They belong to the kingdom Monera and are classified as bacteria because they resemble bacteria when observed under a microscope. 

Apart from this, they are completely distinct from prokaryotes. However, they share slightly common characteristics with the eukaryotes.These can easily survive under very harsh conditions such as the bottom of the sea and the volcanic vents and are thus known as extremophiles. 

Few characteristics of archaeabacteria

Archaebacteria are obligate or facultative anaerobes, i.e., they flourish in the absence of oxygen and that is why only they can undergo methanogenesis.

The cell membranes of the Archaebacteria are composed of lipids.

The rigid cell wall provides shape and support to the Archaebacteria. It also protects the cell from bursting under hypotonic conditions.

The cell wall is composed of Pseudomurein, which prevents archaebacteria from the effects of Lysozyme. Lysozyme is an enzyme released by the immune system of the host, which dissolves the cell wall of pathogenic bacteria.
