Solution

The correct option is D DNA made from a mature mRNA template
The complementary DNA or cDNA is synthesized, or manufactured from an mRNA or messenger RNA template. It is synthesized in a reaction that is catalyzed by the reverse transcriptase and DNA polymerase enzymes.
So, the correct option is 'DNA made from a mature mRNA template'.
