Final answer:
The worst case time complexity for the GET operation in a linked list is O(N), as you may need to traverse the entire list to reach the requested element.
Step-by-step explanation:
The student has asked about the worst case time complexity of the GET operation in a linked list that contains N elements. To retrieve an element at a certain position using the GET operation in a linked list, you need to traverse the list from the head to that position. This means that in the worst case, you could potentially traverse the entire list if the needed element is at the end or not present, leading to a time complexity of O(N).
