Solution

The correct option is A 23S rRNA
The 23S rRNA is a 2904 nucleotide long component of the larger subunit of the bacterial ribosome. The ribosomal peptidyl transferase activity resides in domian V of this rRNA, and this domain is the most common binding site for antibiotics that inhibit translation.
