Best answer
Right option is (b) 55S

The best explanation: Eukaryotes consists of two types of the ribosome, cytosolic and organellar. The cytosolic ribosome is of 80S while organellar ribosome of mitochondria and chloroplast is smaller in size than cytosolic ribosome and bear resemblance to bacterial ribosome.
