" As we follow along on a cladogram, it will split at nodes into two or more internodes a specitation event (the formation of new species). The line between two specification events, the internode, represents at least one hypothetical ancestor."

The node in a cladogram represents the formation of a new species. The formation of a new species is termed as a speciation event. The node in  cladogram  indicates the point at which a splitting event,  or formation of a new species occurred. The line between two nodes is called the internode. It represents at least one hypothetical ancestor.A cladogram is a tree shaped diagram that is used to illustrate evolutionary relationships among species by analyzing some similarities or differences in physical features and other kinds of characters in the organisms.

The question is asking :"What do the “nodes” in a cladogram represent? In a way, they do represent "union", but what does this union mean in the sense of the cladogram? It means a point when the two species were still one species, and it is represented by the last common ancestor - so the correct answer is:The common ancestor
