Solution

The correct option is B RNA
Retrovirus is a virus that is composed not of DNA but of RNA. Retroviruses have an enzyme, called as reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell. The retroviral DNA can then integrate into the chromosomal DNA of the host cell, to be expressed there. HIV is a retrovirus.
