  • A O(1) ✔ ✖
  • B O(log n) ✔ ✖
  • C O(n) ✔ ✖
  • D O(n log n) ✔ ✖
Correct Answer: Option A

Explanation

In a stack implemented using a singly linked list, the pop operation removes the top element from the stack. Since the linked list maintains a reference to the top node, the pop operation can be performed in constant time by updating the reference to the next node. Thus, the time complexity of the pop operation is O(1).
