DNA Replication and Gene Expression in Archaeans More Closely Resemble

DNA replication and gene expression in archaeans more closely resemble eukaryotic cells than the same processes in bacteria. However both Bacteria and Archaea are prokaryotic. What does this suggest?

A) Eukaryotic cells are descended from modern Archaeans.
B) Bacterial cells are not related to Archaeans.
C) Eukaryotic cells shared a more recent common ancestor with Archaeans than with bacterial cells.
D) There must have been 2 origin events, one producing the bacteria and the other producing Archaeans and eukaryotic cells.
