Answer:
The correct answer is C eukaryotes have a greater variety of genetic material than prokaryotes.
Explanation:
Prokaryotic cells consist of single chromosome and their DNA is present in a dense region called nucleoid.As one copy of each gene is present in the chromosome prokaryotic cells are haploid.The DNA of prokaryotic cells are circular
Whereas eukaryotic DNA is linear and multiple distinct chromosomes are present in eukaryotes.Two copies of each chromosome are present are in many eukaryotic cells.As a result the eukaryotic cells are diploid in nature.
Due to this greater variety of genetic material the domain eukarya are more complex than archea and or bacteria domains.
