### Understanding LIFO Principle
The Last In First Out (LIFO) principle means that the last element added to a structure is the first one to be removed. This is akin to a stack of plates: you add to the top and also remove from the top.

### Analysis of Each Data Structure
1. **Queue**: Operates on a First In First Out (FIFO) basis. Elements are added at the back and removed from the front.
2. **Stack**: Follows the LIFO principle. Elements are pushed onto the top and popped from the top.
3. **Linked List**: This is a more general structure. It can be manipulated in various ways, but it doesn’t inherently enforce LIFO unless specifically implemented as such (for example, a linked list can be used to implement a stack).
4. **Binary Search Tree**: This is not related to LIFO. It’s a tree structure where each node has at most two children, ordered by the values of the nodes.

### Conclusion
Among the options provided, the **Stack** is the only data structure that uses a Last In First Out (LIFO) ordering principle.
