Which node in a tree represents the generation of the node ?OptionsHeight of a nodeOrder of a nodeDegree of a nodeLevels of a node

To determine which option represents the generation of a node in a tree, we first need to understand the meanings of each term in the context of tree structures.

1. Height of a Node: The height of a node is the length of the longest path from that node to a leaf. It does not represent generation but rather depth.

2. Order of a Node: The order of a node typically refers to the number of children that a node has. This again does not indicate generation.

3. Degree of a Node: The degree of a node is the total number of children that node has. It relates more to the branching nature of the node rather than its generational position.

4. Levels of a Node: In tree terminology, the level of a node refers to its position relative to the root. It is usually defined as the number of edges from the root to the node, which does correspond to the generation of the node—specifically, how far away it is from the root or from a particular ancestor.

Based on the definitions:

Final Answer

The node in a tree that represents the generation of the node is Levels of a node.
