It is made up of two subunits-. Large subunits- join amino acids to form a polypeptide chain. Small subunits- reads RNA. In prokaryotes, the subunits are 50S and 30S whereas, in eukaryotes, it is 60S and 40S. So, the correct answer is 'Two subunits'.

Each ribosome is composed of small (30 S) and large (50 S) components, called subunits, which are bound to each other: (30S) has mainly a decoding function and is also bound to the mRNA (50S) has mainly a catalytic function and is also bound to the aminoacylated tRNAs.
