c. Splicing machinery for introns

Explanation:

Eukaryotes have introns in their genes. Introns are not present in the genes of bacteria but are present in the genes of archaea. Therefore, bacteria lack the proteins required for the removal of introns from the primary transcript after the process of transcription. The presence of introns in both eukaryotic and archaeal genes requires the presence of splicing proteins. These splicing proteins remove the introns and ligate the exons in a specific sequence during post transcription modification.
