Solution
The correct option is A rRNA
Ribosomal ribonucleic acid (rRNA) is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms. It constitutes the predominant material within the ribosome, which is approximately 60% rRNA and 40% protein by weight. Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA. Molecules of tRNA are formed in the nucleus and migrate into the cytoplasm. mRNA is made in the nucleus. DNA is also formed in nucleus.
