Answer
Both A and R are true and R is the correct explanation of A.
Explanation
An element in a stack is removed from its top. The stack follows the Last-In-First-Out (LIFO) approach, where the last element added (the top element) is the first one to be removed. The process of removing an element from a stack is called pop.
