Nucleolus
Dark-staining, spherical body in the nucleus that produces ribosomal subunits.
Ribosomal RNA
RNA molecules that form the core of the ribosome, playing a crucial role in the synthesis of proteins.
Transfer RNA
A type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein during protein synthesis.

Final Answer :
A
Explanation :
Ribosomal RNA (rRNA) is produced in the nucleolus, which is a region of the nucleus. The nucleolus is responsible for the transcription and processing of rRNA, which is a structural component of ribosomes along with proteins. Transfer RNA (tRNA) and messenger RNA (mRNA) are produced in the nucleus, but not specifically in the nucleolus. Primary mRNA transcripts are also produced in the nucleus, but are further processed and modified in the cytoplasm. Ribozymes are not a class of RNA molecules produced in the nucleolus.
