Answer:
D) choose the tree that represents the fewest evolutionary changes, either in DNA sequences or morphology.
Explanation:
Parsimony is a concept applied while constructing a phylogenetic tree. According to it the best tree is constructed by fewest evolutionary changes, either in DNA sequence or morphology. Complicated changes should be present as less as possible in a tree.
For example, suppose vertebrate relationship can be explained using two trees. Tree A has six evolutionary changes and evolution of bony skeleton occurs once. Tree B has seven evolutionary changes and evolution of bony skeleton occurs twice at different spots. Tree A will be preferred because it explains the vertebrate relationship in a less complicated way than Tree B.
