Which statement about herpes antiviral therapy is true?

Explanation:
Herpes antiviral therapy relies on nucleoside analogs that selectively block viral DNA replication. Acyclovir, Valacyclovir, and Famciclovir are in this class: acyclovir is activated in infected cells by viral thymidine kinase and then inhibits viral DNA polymerase; valacyclovir and famciclovir are prodrugs that improve oral bioavailability and are converted to active forms that do the same job. These drugs are effective against herpes simplex virus types 1 and 2 and varicella-zoster virus. The other options are agents for influenza or fungi, not herpesviruses, so they aren’t appropriate treatments for herpes infections.
