E) None of the above

There is a high degree of lateral gene transfer in prokaryotes, which makes constructing phylogenies more difficult. Mammal phylogenies are based on DNA evidence, not RNA. The presence of lateral gene transfer in mammals is much lower than in prokaryotes. The simplicity of the phylogenetic reconstruction process is not determined by organism size.
