Solution

The correct option is C It is a site for active ribosomal RNA synthesis.

  • Nucleolus is the spherical structure present in the nucleoplasm. 
  • It is not membrane-bounded and thus its content is continuous with nucleoplasm. It gets disappear during cell division.
  • But it provides the site for ribosomal RNA synthesis and also takes part in protein synthesis. 
    Hence, option C is correct.
