Which of the following data structures is best suited for implementing a breadth-first search (BF

A Queue is the most suitable data structure for implementing a Breadth-First Search (BFS) algorithm. In BFS, nodes of a graph are explored level by level, starting from a source node. A queue is used to keep track of nodes to be explored next, ensuring that nodes are visited in the correct order (FIFO: First In, First Out). As BFS explores all neighbors of a node before moving to the next level, a queue maintains this order efficiently. Why Other Options Are Wrong : A) A Stack is used for Depth-First Search (DFS), where nodes are explored deeply before moving to the next branch. C) Hash Tables are used for quick lookups and do not maintain a specific traversal order. D) A Binary Search Tree is used for sorted data and is unrelated to BFS. E) Linked List lacks the FIFO property required for BFS traversal.
