Given two vertices in a graph s and t, which of the two traversals (BFS and DFS) can be used to find if there is a path from s to t ?
Answer: C. Both BFS and DFS — Both BFS and DFS can determine if a path exists between two vertices s and t. These traversals explore all reachable nodes from the starting vertex, so if t…

- D.
Neither BFS nor DFS

Correct answer: C
Both BFS and DFS can determine if a path exists between two vertices s and t. These traversals explore all reachable nodes from the starting vertex, so if t is found during traversal, a path exists.
