Which of the following two arrays will Mergesort method sort more efficiently?A) { 5,4,7,9,8,10,3,2,6,1}B) { 4,4,4,4,4,4,4,4,4,4}Question 9 options: Neither) Mergesort runs in the same amount of time regardless of the ordering of the array. A) Mergesort will sort a randomized array in nLog(n) time and an array of duplicates in n^2 time. B) Because our array is all duplicates, Mergesort will recognize that it is already sorted and exit early.

The time complexity of merge sort is O(n*Log n) in all the 3 cases (i.e worst, average, and best) as…
