B Correct answer
Explanation

A retrovirus is an RNA virus, which replicates inside a host cell by the process of reverse transcription. Initially it employs its own reverse transcriptase enzyme to produce DNA from its RNA genome. This is the opposite of the normal pattern and hence, it is called retro or backwards. This new DNA is in turn included into the host's genome by an integrase enzyme.
