Answer:
The correct answer is C. Difference in RNA and makeup of the cell wall.
Step-by-step explanation:
Eubacteria have peptidoglycan in their cell walls, which are also made of mostly proteins, meanwhile Archaebacteria lack this molecule. Also, archaebacteria present introns in their DNA, otherwise, eubacteria don't. These differences can also relate to the habitats where they are usually found. Archaea (Stressful and harmful habitats) and Eubacteria (Not so harmful and mostly average conditions).
