      A O(N) Correct Answer Incorrect Answer
      B O(log N) Correct Answer Incorrect Answer
      C O(1) Correct Answer Incorrect Answer
      D O(N log N) Correct Answer Incorrect Answer
      E O(N^2) Correct Answer Incorrect Answer

      Solution

      In a singly linked list implementation of a stack, the top of the stack is typically represented by the head of the list. Accessing the head element (peek operation) takes constant time, O(1).
