In a mind map, what is the role of the central node?

• A. It stores the text at each sub-node.
• B. It anchors topics by connecting to all nodes and sub-nodes.
• C. It defines the color palette for branches.
• D. It is optional and often omitted.

Answer: (B)

In a mind map, the central node serves as the anchor for the entire diagram. It represents the main topic and acts as the hub from which all topics, subtopics, and ideas radiate. Because it connects to every branch and sub-branch, the central node provides the structure and focal point that organize the map.

Text for sub-nodes lives in those sub-nodes themselves, not in the center. Colors are a styling choice for branches and nodes, not a function of the central node. And the map relies on this central focus; while you could create a map without one in theory, it would lose the clear, organized structure that the central node provides.
