Answer

Answer: (B) 23S rRNA
Peptidyl transferase activity, which catalyzes peptide bond formation during protein synthesis, resides in the 23S rRNA of the large ribosomal subunit. 16S rRNA is involved in mRNA binding, 5S rRNA plays a structural role, and 28S rRNA is part of the eukaryotic ribosome.
