  • A. Virulent phage
  • B. Lytic phage
  • C. Temperate phage
  • D. Both A and B

Explanation

The correct statement is that the phage causing the lysogenic cycle is a "Temperate Phage." Temperate phages can enter the lysogenic cycle, integrating their genetic material into the host genome before transitioning to the lytic cycle.

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.
