C. Hepatitis B and HIV >>> Lamivudine it goes after reverse transcriptase both in Hep B and HIV.

Hepadnaviruses are the only viruses that produce genome DNA by reverse transcription with mRNA as the template. Note that this type of RNA-dependent DNA synthesis is similar to but different from the process in retroviruses, in which the genome RNA is transcribed into a DNA intermediate.

nod The correct answer is C (Hepatitis B and HIV). HBV and HIV encode reverse transcriptases that share sensitivity to lamivudine....(like NNL said)
