What do the “nodes” in a cladogram represent?

In a cladogram, what do the "nodes" represent?

The nodes in a cladogram signify points of divergence where a new species is formed. This process is known as a speciation event, indicating the evolutionary branching from a common 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.

" 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 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
