 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
 A A search method that scans from the root down to the deepest leaf B A search engine like google C A search method that searches the branches only D A search method that searches nodes row by row
Explanation:

Detailed explanation-1: -Breadth-first search (BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.

Detailed explanation-2: -The breadth-first search or BFS algorithm is used to search a tree or graph data structure for a node that meets a set of criteria. It begins at the root of the tree or graph and investigates all nodes at the current depth level before moving on to nodes at the next depth level.

Detailed explanation-3: -Explanation: Breadth First Search can be applied to Bipartite a graph, to find the shortest path between two nodes, in GPS Navigation. In Path finding, Depth First Search is used.

Detailed explanation-4: -Breadth-first search is so named because it expands the frontier between discovered and undiscovered vertices uniformly across the breadth of the frontier.

Detailed explanation-5: -Breadth-first search (BFS) is an algorithm for searching a tree or an undirected graph data structure. Here, we start with a node and then visit all the adjacent nodes in the same level and then move to the adjacent successor node in the next level.
