Answer :
Final answer:
After three iterations of the outer loop, the list [13, 72, 69, 24, 29, 21, 56] will be sorted into [21, 24, 29, 56, 13, 69, 72]. So the option number a is correct.
Explanation:
In order to determine the list after three iterations of the outer loop, we need to understand the basic concept of an outer loop.
The outer loop is used to go through the list and sort the elements in ascending or descending order. In each iteration of the outer loop, the largest or smallest element is moved to the end of the list.
After three iterations of the outer loop on the given list [13, 72, 69, 24, 29, 21, 56], the sorted list would be [21, 24, 29, 56, 13, 69, 72]. Therefore, the correct answer is option A: [21, 24, 29, 56, 13, 69, 72].
