The correct option is C DNA from RNA template
Reverse transcriptase is an enzyme present in viruses having RNA as the genetic material such as retroviruses. They use this enzyme to make DNA from RNA in a process called reverse transcription, this DNA can then be inserted into host DNA.Reverse transcriptase is used in genetic engineering to make complementary DNA(cDNA) from mRNA molecules. This helps to avoid complications arising from intronsequences present in genomic DNA which do not code for any protein.
