The right option is; ribosomes
The organelles that produce proteins used within the cell are the ribosomes.
The ribosome is a membrane bound organelle found within all living cells. The ribosome functions as the site of protein synthesis and it produce proteins by translating messenger RNA. Amino acids are joined together by ribosomes in the order specified by messenger RNA (mRNA) molecules. Ribosomes are composed of two major parts which are; (i) the large subunits, which link amino acids to create a polypeptide chain, and (ii) the small ribosomal subunits, which read the RNA.
