Solution

The correct option is C STATEMENT-1 is True, STATEMENT-2 is False
RNA stands for Ribonucleic acid. It is a nucleic acid, present in all living cells, that plays an essential role in the synthesis of proteins.

On hydrolysis, they yield the pentose sugar ribose, the purine bases adenine and guanine, the pyrimidine bases cytosine and uracil, and phosphoric acid.
In pentose sugar, at the 2nd carbon hydroxyl group is present.

Hence, option C is correct.
