    D. Nucleolus
    Explanation
    The nucleolus is a dark structure found in the nucleus that is responsible for producing parts of the ribosomes. Ribosomes are essential for protein synthesis in the cell. The nucleolus contains ribosomal RNA (rRNA) and proteins, which combine to form ribosomes. These ribosomes then move out of the nucleolus and into the cytoplasm, where they play a crucial role in protein synthesis. Therefore, the nucleolus is the correct answer as it is directly involved in the production of ribosomal components.
