Question:

Which of the following data structures uses the Last-In, First-Out (LIFO) principle for adding and removing elements?

Options:

    
• A) Queue
    
• B) Stack
    
• C) Linked List
    
• D) Binary Search Tree

Correct Answer: B) Stack

Explanation:

A Stack is a linear data structure that follows the Last-In, First-Out (LIFO) principle. This means that the last element added to the stack is the first one to be removed. Standard operations on a stack include push (to insert an element) and pop (to remove the most recently added element).

Why other options are incorrect:

    
• A) Queue: Follows the First-In, First-Out (FIFO) principle, where elements are removed in the same order they were added.
    
• C) Linked List: A sequential collection of data elements where order is determined by pointers rather than physical placement, allowing insertions and deletions at any position.
    
• D) Binary Search Tree: A hierarchical, non-linear node-based structure that maintains sorted data using left and right child pointers rather than LIFO ordering.
