None of the above

Detailed explanation-1: -Hidden Viruses: Other viruses do not immediately become active. Instead, they “hide” for a while. After a hidden virus enters a host cell, its genetic material becomes part of the cell’s genetic material. The virus does not appear to affect the cell’s functions and may stay in this inactive state for years.
Detailed explanation-2: -Such viruses are called “latent, ” and include Epstein-Barr virus (EBV), Varicella-Zoster virus (VZV), HIV, Herpesviruses, and Cytomegalovirus (CMV). When they come out of hiding, or “reactivate, ” latent viruses can cause transient (temporary) symptoms or persistent disease.
Detailed explanation-3: -Virus genomes All viruses have genetic material (a genome) made of nucleic acid. You, like all other cell-based life, use DNA as your genetic material. Viruses, on the other hand, may use either RNA or DNA, both of which are types of nucleic acid.
Detailed explanation-4: -When a virus is present in the body but exists in a resting (latent) state without producing more virus. A latent viral infection usually does not cause any noticeable symptoms and can last a long period of time before becoming active and causing symptoms.
