Solution
The correct option is B Retrovirus
A retrovirus is a single-stranded positive-sense RNA virus with a DNA intermediate. Most of a tumour causing viruses are retroviruses. After infecting a cell a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA by the process reverse transcription. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV virus that causes AIDS is a retrovirus. So, the correct answer is 'Retrovirus'.
