Solution
The correct option is C Viruses
Viruses are considered to be acellular as they do not have a defined cell wall, cell membrane, nucleus or nucleoid, cytoplasm, and cellular organelles. For this reason, they cannot perform their metabolic activities on their own and are obligately dependent on the host cell machinery. Therefore, they do not find a place in the five-kingdom classification system. A. Bacteria are classified under Kingdom Monera as they have a prokaryotic cell.B. Lichens are grouped under Kingdom Fungi.C. Cyanobacteria are photosynthetic prokaryotes grouped under Kingdom Monera.D. No kingdom is ascribed to the viruses.Hence, the correct answer is 'Viruses.'
