Which type has 80S ribosomes?

Explanation:
Ribosome size reflects the organism type: eukaryotic cells use cytosolic ribosomes that are 80S, made up of a large 60S subunit and a small 40S subunit. Prokaryotic cells, on the other hand, have 70S ribosomes composed of 50S and 30S subunits. Because 80S ribosomes are characteristic of eukaryotes, the correct choice points to a eukaryotic type. (Note that some organelles within eukaryotes, like mitochondria and chloroplasts, have 70S ribosomes, reflecting their bacterial ancestry, but the main cytosolic ribosomes are 80S.)
