Correct Option: B

Peptidyl transferase is an amino acyltransferase and forms peptide links between adjacent amino acids using tRNA during translation process. This peptidyl transferase activity is mediated by 23 ribosomal RNA. This ribozyme 23 rRNA is the transferase component in bacteria. Also in eukaryotic cells, the same 23 rRNA holds the subunit containing peptidyl transferase component acting as the ribozyme.
