The correct answer is: B.To make ribosomes

The nucleolus is a structure within the nucleus of eukaryotic cells, and its primary role is to synthesize and assemble ribosomal RNA (rRNA). It is also responsible for combining rRNA with proteins to form the subunits of ribosomes. These ribosomal subunits are then transported out of the nucleus and into the cytoplasm, where they combine to form functional ribosomes, which are essential for protein synthesis.

Here’s why the other options are incorrect:

A.To store RNA: While the nucleolus is involved in the production of rRNA, it does not store RNA in the way the nucleus stores DNA. ...
