Which type of RNA associates with proteins to form ribosomes?

Explanation:
Ribosomes are built from a combination of proteins and ribosomal RNA, with rRNA playing a central role. The rRNA not only provides the structural framework for the ribosome but also forms the catalytic center that links amino acids together during protein synthesis. That makes rRNA the RNA that associates with proteins to form ribosomes. In contrast, mRNA carries the genetic code, tRNA brings amino acids to the growing chain, and small nuclear RNA is involved in RNA processing, not ribosome assembly.
