Explanation:
RNA molecules are single stranded, not included double stranded RNA structures from self folding, and DNA molecules are double stranded. It is thus believed that RNA molecules was the original genetic material and eventually DNA evolved from RNA and overtook RNA as the genetic material given DNA enhanced stability. Thus the answer has to be RNA.
