Answer:
The answer is very likely C.
Explanation:
This becomes easy once we remember that DNA and RNA are not identical - which is why they have different names, RNA = 'ribo', DNA = 'deoxy.' This eliminates choice (A). While they are different, they are not incredibly different - DNA and RNA are both made up of nucleotides - they are not however, made up of Amino acids. Amino acids are what they can <em>code</em> for, and subsequently create proteins during protein synthesis. This helps us eliminate (B). Finally, we know that in order for something to have base <em>pairs</em> it needs to be double stranded - which RNA is not. Which means that because RNA is not double stranded (its singly stranded) that the answer cannot be (D). Leaving us with the only plausible option; (C).
Water is the answer. Water makes up form 60 to 70 percent of our body.
