In a Cladogram,clades Are Groups of Related Organisms

In a cladogram,clades are groups of related organisms.In the past,phylogeneticists built clades using the idea of parsimony,that the pattern that uses the fewest evolutionary changes is the most likely to be correct.Today with the use of computers and DNA sequences the explanation that is thought to be the best is

A) One that shows the most changes in nucleotide sequences.
B) One that eliminates any similar DNA sequences.
C) One that shows the DNA unique to that species.
D) One that shows the fewest changes in the nucleotide sequences.
E) Still one that uses the same system of parsimony.
