For implementing push and pop operations of a stack data structure, we need to add elements to the top of the stack and remove elements from the top of the stack. This can be achieved by adding elements to the beginning of the list using addFirst() operation and removing elements from the beginning of the list using removeFirst() operation. Therefore, II(addFirst) and III(removeFirst) are the best choices for implementing push and pop operations respectively.
