Answer 2

Answer:

B. It is a single-stranded molecule

Explanation:

Unlike DNA, RNA is usually single stranded and can folds back upon itself forming a secondary structure known as Hairpin loop. DNA is double stranded. In this way both RNA and DNA become more stable and are prevented from forming bonds with other molecules.
