Solution

The correct option is C Introns absent in cDNA
Complementary DNA is DNA synthesized from a messenger RNA (mRNA) template in a reaction catalyzed by the enzymes reverse transcriptase and DNA polymerase.
cDNA is often used to clone eukaryotic genes in prokaryotes. The specialty of cDNA is that it does not contain introns.
