B: Integration of phage nucleic acid to host bacteria genome
Answer: B: Integration of phage nucleic acid to host bacteria genome 
Explanation: Ref: PubMed* Lysogenic conversion is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome.* Once the genetic material of phage bacteria is introduced, the host bacterium continues to live and reproduce normally.* The genetic material of the bacteriophage, called a prophage, can be transmitted to daughter cells at each subsequent cell division, and a later event (such as UV radiation or the presence of certain chemicals) can release it, causing proliferation of new phages via the lytic cycle.* For example, a number of strains of the diphtheria bacillus acquire the capacity to form diphtheria toxin immediately after penetration of the phage into the cell and retain that capacity until the moment of the cells dissolution (lysis).
