Solution
The correct option is D Nucleolus
Ribosomes are naked ribonucleoprotein particles made up of rRNA and proteins. The nucleolus is naked, roughly round, darkly stained structure that is attached to chromatin at a specific spot called as Nucleolar Organising Region. The nucleolus is the site of rRNA synthesis and, hence, synthesis of ribosomes. It is, therefore, called as ribosomal factory. Ribosomal proteins are, however, synthesized in the cytoplasm. Thus, the correct answer is option C.
