The correct option is C nucleolus
Ribosomal ribonucleic acid is a type of non-coding RNA that is a component of ribosomes that carry out the synthesis of proteins.
rRNAs combine with proteins to form ribosomes, which accounts for approximately 80% of the total RNA present in the cell. Molecules of rRNA are synthesised in a special compartment of the cell called the nucleolus, which is located in the core of the nucleus. Ribosomal RNA synthesis by Pol-I occurs in the nucleolus. The pre-rRNA transcripts are then processed and yield the mature rRNAs.
A nucleosome is the basic structural unit of DNA packaging in eukaryotes, where DNA is wrapped around the core of histone proteins.
The lysosome is a membrane-bound cell organelle filled with different digestive enzymes.
