Archaebacteria, also known as Archaea, are a group of microorganisms that are similar to bacteria but are different in several key aspects.

1) Composition of cell wall: The cell walls of Archaea are fundamentally different from those found in other bacteria. While most bacteria have cell walls made of peptidoglycan, Archaea do not. Instead, their cell walls are often composed of a variety of other substances, including proteins, glycoproteins, and polysaccharides.

2) Composition of genetic material: The genetic material of Archaea is also different from other bacteria. While both groups have circular DNA, the DNA of Archaea is more similar to that of eukaryotes in terms of its replication and transcription mechanisms.

3) True nucleus: This statement is incorrect. Like other bacteria, Archaea do not have a true nucleus. Instead, their DNA is contained within a region of the cell called the nucleoid.

4) All of these: Based on the above explanations, the correct answer is not "All of these" because Archaea do not have a true nucleus. So, the correct answer is a combination of the first two options: the composition of the cell wall and the composition of the genetic material.
