Solution

The sorting algorithm that can be used to sort a linked list in O(n log n) time is Merge sort.

Here's why:

  1. Insertion Sort: It takes O(n^2) time in worst case. This makes it inefficient for large lists.

  2. Bubble Sort: It also takes O(n^2) time in worst case. This makes it inefficient for large lists.

  3. Merge Sort: It takes O(n log n) time in all cases. Merge sort is often preferred for sorting a linked list as it has a good worst-case time complexity and it does not require random access to elements.

  4. Quick Sort: The worst case time complexity of Quick Sort is O(n^2). Also, Quick sort requires a lot of this kind of direct access. In linked list to access an element we need to traverse from the head to the
