Explanation:

Ribosomes, centrosomes are the non-membranous structures. Ribosomes are found in both eukaryotic and prokaryotic cells. In prokaryotes 70s ribosomes are present and in eukaryotes 80s ribosomes are present. Prokaryotes do not have a membrane-bound nucleus and organelles.
Ribosomes helps in protein synthesis in both prokaryotes and eukaryotes. Therefore the right answer is the ribosome.
