Phages which show lysogenic cycle are known as:
Correct answer: C. Temperate phages
- A. Enveloped Phage
- B. Virulent Phage
- C. Temperate phages
- D. Bacteriophage
Explanation
Temperate phages are some bacteriophages which display a lysogenic life cycle. Lysogeny is characterized by an integration of the bacteriophage nucleic acid into the host bacteria genome and becomes prophage. In this condition, the bacterium continues to live and reproduce normally. Bacteriophages that only use the lytic cycle are called virulent phages. So, the correct answer is 'temperate phages'.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
