``` 1 for each j, from 1 to the length of A – 1 2 temp = A[ j ] 3 i = j – 1 4 while i is greater than -1 and A[ i ] is greater than temp 5 A[ i + 1 ] = A[ i ] 6 i— 7 A[ i + 1] = temp ``` A. It tells us that the time complexity of insertion sort is always O( n ). B. It can help us to analyze the time complexity of insertion sort, as long as this number can be put in terms of n. C. It tells us that the time complexity of insertion sort is always O( n2 ). D. It goes to show how much memory space is conserved with insertion sort.
