A stack is a data structure that follows the Last In, First Out (LIFO) principle, allowing operations only at one end: push (add an item) and pop (remove the top item). The operations described in A, B, and C do not adhere to this principle, as they involve accessing or modifying elements at arbitrary positions or specific values, which are not standard stack operations.
