Show answer & explanation
Correct answer: A
DFS detects cycles by identifying back edges during traversal, making statement A correct.
It visits all reachable vertices to identify connected components, validating statement B.
DFS functions on both directed and undirected graphs as stated in C.
However, BFS guarantees shortest paths in unweighted graphs, not DFS, invalidating statement D.
Therefore, the correct combination includes A, B, and C.
