Answer : 3. "Eubacteria"
Explanation :
Answer: C) Eubacteria Explanation: There are two kingdoms of bacteria. They are 1. Eubacteria┬а and┬а 2. Archaea ┬а The members of these two kingdoms appear similar in shape and appearance, even under the extreme magnification of the electron microscope . However, they are very different from each other in a number of molecular and biochemical aspects. It is these differences that have resulted in the microorganisms being grouped into separate kingdoms. ┬а For example, eubacteria contain the rigid, stress-bearing network known as the peptidoglycan . The only exceptions are the bacteria from the genera Mycoplasma and Chlamydia. Archaebacteria do not contain peptidoglycan. Instead, they contain a different structure that is called pseudomurein. ┬а The common bacteria belongs to Eubacteria kingdom.
