A researcher is studying two different viruses: Virus A is a DNA bacteriophage that undergoes the lysogenic cycle, and Virus B is an RNA retrovirus that infects mammalian cells. After several generations, the researcher notices that Virus B has accumulated significantly more genetic mutations than Virus A.Which combination of factors BEST explains this observation?

A virology student is comparing three viruses: Virus X has a helical capsid and causes immediate cell rupture upon release; Virus Y has an icosahedral capsid with an envelope and exits by budding; and Virus Z is an oncogenic virus with complex capsid structure.Based on these characteristics, which statement about host range, infection mechanisms, and cellular outcomes is MOST accurate?
