Which data structure uses linked nodes?

  1. Trees

  2. Graphs

  3. Arrays

  4. Sets

The correct answer is: Trees

Trees use linked nodes to connect parent nodes to child nodes, forming a hierarchical structure. Graphs, on the other hand, use edges and vertices to represent relationships, and do not necessarily use linked nodes. Arrays use a linear structure with indices, while sets are collections of distinct items with no specific order. Therefore, the data structure that uses linked nodes is a tree.
