A clade is a grouping that includes a common ancestor and all the descendants of that ancestor. A key feature of a clade is that a common ancestor and all its descendants are part of the clade.
Cladograms emphasize the sequence or order in which derived characters arise from the central phylogenetic tree and thus data for cladograms is present in the cladistics.
Cladistics is now the most commonly used methods to classify organisms.
So the correct option is All of the above.
