Answer:
The correct answer will be option-D.
Explanation:
Ribosomes are the machinery which is involved in the synthesis of proteins through translation.
The ribosomes are found in the cell either in the free form in the cytoplasm or the attached form to the endoplasmic reticulum. The ribosomes are made up of two subunits the large and the small subunit which is made up of the rRNA and the proteins. The subunits of the ribosomes interpret the instructions of the mRNA and synthesizes the proteins.
