Assertion (A): A Stack is a linear data structure that stores the elements in First In, First Out order.

Reasoning (R): In Stack, a new element is added and removed from one end only.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

A is false but R is true.

Explanation
A stack is a linear data structure that stores elements in LIFO (Last In, First Out) order, where the last element added to the stack is the first one to be removed. In a stack, a new element is added and removed from only one end, which is the top of the stack.
