RNA Differs from DNA in That RNA Possesses a Hydroxyl

RNA differs from DNA in that RNA possesses a hydroxyl group on the 2'-carbon atom of its sugar, contains uracil instead of thymine, and is normally single stranded. Several classes of RNA exist within bacterial and eukaryotic cells.
-Which class of RNA is correctly paired with its function?

A) Small nuclear RNA (snRNA) : processes rRNA
B) Transfer RNA (tRNA) : attaches to an amino acid
C) MicroRNA (miRNA) : carries information for the amino acid sequence of a protein
D) Ribosomal RNA (rRNA) : carries out RNA interference
