Solution

The BFS (Breadth-First Search) traversal of a graph will result into a Queue. So, the answer is c) Queue.

Here's why:

  1. BFS starts traversal from the root node (or any arbitrary node of a graph, also termed as the 'source node') and visits nodes in a level by level manner (i.e., visiting the ones closest to the root first).

  2. It uses a Queue data structure to remember to get the next vertex to start the search when a dead end occurs in any iteration.

  3. We insert the source node into the queue. Then we start a loop until the queue is empty. In each iteration of the loop, we remove a vertex from the queue and insert all its not yet visited neighbors into the queue.

  4. As a result, we get a queue that represents the BFS traversal of the graph.
