Solution

The correct option is A In mitochondria
Eukaryotes have 80s ribosomes respectively comprising of little (40s) and substantial (60s) subunits. The ribosomes seen in the chloroplasts of mitochondria of eukaryotes are comprised of big and little subunits composed of proteins inside a 70s particle.
Thus A is the correct answer.
