The diagram shows an intron-exon structure, which is characteristic of eukaryotic DNA. Bacteria and archaea typically have simpler DNA structures without introns. The process being diagrammed is splicing, which is the removal of introns and joining of exons to produce a mature mRNA molecule. This process is unique to eukaryotes, as bacteria and archaea do not have introns to remove. Therefore, the best choice is C, eukaryote splicing.
