The structure of virus is very simple and the virion contains single molecule of nucleic acid which is covered by a coat of protein known as capsid.
The viruses may contain DNA or RNA any one of them. They never contain both DNA as well as RNA and its nucleic acid is either single stranded or double stranded.
Therefore, the function of reverse transcriptase in retroviruses is it uses viral RNA as a template for DNA synthesis.Thus, option A is correct.
