Archaea are different from bacteria in that archaea a. have structures that are more similar to bacterial structures. b. have molecules that are different from eukaryotic molecules. c. have structures and molecules that are more similar to eukaryotes than bacteria. d. developed before bacteria.

A i wrong because it says that they are similar.

B is wrong because archaea are phylogenetically similar to eukaryotes

C is also true because archaea are more phylogenetically similar to eukaryotes than bacteria

D is true because the Archaea did develop before Bacteria
