To determine where rRNA is synthesized, we analyze each option:

• Mesosphere: A layer of the Earth's atmosphere, not related to cellular rRNA synthesis.
• Nucleolus: A structure within the nucleus of a cell, known to be the site of rRNA synthesis and ribosome assembly.
• Golgi bodies: Involved in processing and packaging proteins, not rRNA synthesis.
