Solution

The correct option is C cDNA
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase. cDNA is often used to clone eukaryotic genes in prokaryotes. cDNA is also produced naturally by retroviruses (such as HIV ) for integration into the host's genome.

So, the correct option is 'cDNA'.
