Answer: The correct answer is-

1) Cladogram

2) Molted external skeleton and segmentation.

A cladogram can be described as a diagrammatic representation in a  branching treelike form, which is used to depict phylogenetic relationships among different species.

For every divergence point in a cladogram, the two branching lines show descendance, which indicates divergence of species from a common ancestor. Thus, it is a system of grouping of various organisms.

In the given cladogram, the two characteristics that are shared by crabs and barnacles but not by limpets are Molted external skeleton and segmentation.
