An enzyme that helps in the conversion of RNA to DNA is called:

Explanation

Option A, transcriptase, is an RNA dependent RNA polymerase, which forms RNA strands by using RNA strands as a template. Option B, polymerase, can either be DNA polymerase or RNA polymerase, resulting in a complementary strand of DNA or RNA from a particular template strand. Option C is the correct answer, as reverse transcriptase is an RNA-dependent DNA polymerase, as it uses RNA as a template to form a DNA copy. This enzyme is the principal enzyme in retroviruses such as HIV. Option D, synthetase, is any enzyme that results in the synthesis of many different compounds, and is not specific to DNA or RNA.
