None of the above

Detailed explanation-1: -HIV enters a special type of lytic cycle, although some aspects of its replication process are similar to the lysogenic cycle. It should be noted that only bacteriophages, viruses that infect bacteria, undergo the lysogenic cycle.
Detailed explanation-2: -For instance the AIDS viruses can either infect humans (or some other primates) lytically, or lay dormant (lysogenic) as part of the infected cells’ genome, keeping the ability to return to lysis at a later time.
Detailed explanation-3: -Lysogenic cycle. The lysogenic cycle allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( ), can switch between the two cycles.
Detailed explanation-4: -An example of a lysogenic bacteriophage is the (lambda) virus, which also infects the E. coli bacterium. Viruses that infect plant or animal cells may sometimes undergo infections where they are not producing virions for long periods.
