What is the average case running time of an insertion sort algorithm?(

1.	What is the average case running time of an insertion sort algorithm?(a) O(N)(b) O(N log N)(c) O(log N)(d) O(N^2)I had been asked this question at a job interview.This intriguing question comes from Insertion sort in chapter Sorting of Data Structures & Algorithms II
Answer» Correct choice is (d) O(N^2) The best I can explain: The AVERAGE CASE analysis of a tight bound ALGORITHM is MATHEMATICALLY achieved to be O(N^2).
