Show answer & explanation

Correct answer: D

A Queue follows the FIFO (First-In, First-Out) principle. Breadth First Search (BFS) explores a graph level-by-level, requiring nodes of the current level to be processed completely before moving to the next. A queue is uniquely suited to keep track of these nodes in the exact order they are discovered.
