Which of the following best compares Linnaean taxonomy with Cladistics?

a.) Cladistics is impractical when trying to classify millions of species, whereas the Linnaean taxonomic system allows for multiple possibilities for organization and no limits to the size of the hierarchy.

b.) Linnaean taxonomy organizes living things based on genetic traits and evolutionary history, whereas Cladistics uses a fixed number of clades, or branches, by which organisms are classified.

c.) Linnaean taxonomy uses obvious physical similarities to group organisms into an evolutionary framework, whereas Cladistics does not take physical traits into account.

d.) Cladistics provides possible evolutionary explanation of physical traits in organisms, whereas Linnaean taxonomy groups organisms based on physical traits though they may not be related.
