Which of the following best describes the working mechanism of the Depth First Search (DFS) algorithm in graph traversal?
Answer: D. DFS explores as far as possible along each branch before backtracking. — Depth First Search (DFS) explores a graph by traversing as far as possible along each branch before backtracking. It uses a stack (either explicitly or via…
- A.
DFS follows a level-by-level approach using a queue.
- B.
DFS visits all vertices at the same level before going deeper.
- C.
DFS always identifies the shortest path first.
- D.
DFS explores as far as possible along each branch before backtracking.

Correct answer: D
Depth First Search (DFS) explores a graph by traversing as far as possible along each branch before backtracking. It uses a stack (either explicitly or via recursion) to keep track of nodes to visit next.
