What are the two types of nucleic acids and what are their functions?

I - DNA is a huge molecule that stores genetic information and regulates protein production.
II - RNA is a polynucleotide formed by a single chain that can be linear or adopt particular structures, and it has three types: ribosomal RNA, messenger RNA, and transfer RNA.
III - Both DNA and RNA are formed by nucleotides, which can polymerize through condensation reactions.
IV - The energy stored in the high-energy bonds of ATP can be used by the cell when metabolic activities require it.
a) I and II are correct.
b) II and III are correct.
c) I, II, III, and IV are correct.
d) Only IV is correct.
