The algorithm that has a worst case complexity of O(n log2n) is B. Merge Sort.

Here's a brief explanation:

A. Selection Sort: This algorithm has a worst-case and average time complexity of O(n^2), for a list with n items.

B. Merge Sort: This algorithm has a worst-case time complexity of O(n log n). It's a divide and conquer algorithm that splits a list in half, and keeps splitting the list by 2 until it only has singular elements.

C. Bubble Sort: This algorithm also has a worst-case and average time complexity of O(n^2), where n is the number of items being sorted.

D. Insertion Sort: This algorithm has a worst-case time complexity of O(n^2) due to the two nested loops.

E. None of the above: This option is incorrect as Merge Sort has a worst-case time complexity of O(n log n).
