A. Viruses sometimes transfer information from RNA to DNA.

Explanation:

An RNA virus is a virus that uses ribonucleic acid (RNA) as a genetic material, or that in its replication process needs RNA. For example, the Hepatitis B virus is a virus classified as a DNA virus (hepadnavirus), with the peculiarity of having its double-stranded DNA genome and the genome is transcribed into RNA during replication.Its nucleic acid is usually single stranded RNA but it can also be double stranded RNA. Single-stranded RNA viruses can, in turn, be classified according to the sense or polarity of their RNA as negative or positive. The positive RNA viruses are identical to the viral mRNA and therefore can be immediately translated by the host cell. The negative viral RNA is complementary to the mRNA and therefore must become RNA positive by an RNA polymerase before translation
