The correct answer is C. ribosome.

Ribosomes are responsible for protein synthesis in a cell. They are small, specialized organelles composed of RNA and protein. Ribosomes can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum (ER). They play a crucial role in translating the genetic information encoded in messenger RNA (mRNA) into protein sequences. Ribosomes facilitate the assembly of amino acids into polypeptide chains, which eventually fold into functional proteins.
