Biomolecules

Explanation: 

(i) RNA is a nucleic acid that is composed of nucleotides. Each RNA nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil), a ribose sugar, and a phosphate group.

(ii) RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar-phosphate backbone of RNA is broken, cleaving the RNA molecule. RNA is susceptible to this base-catalyzed hydrolysis because the ribose sugar in RNA has a hydroxyl group at the 2′ position.

The complete hydrolysis of DNA yields β-D-2-deoxyribose, phosphoric acid, and nitrogen-containing heterocyclic compounds.

So, option 3 is the correct answer.
