Explanation: 

Detailed explanation-1: -To perform an insertion sort, begin at the left-most element of the array and invoke Insert to insert each element encountered into its correct position. The ordered sequence into which the element is inserted is stored at the beginning of the array in the set of indices already examined.

Detailed explanation-2: -Statement 1: In insertion sort, after m passes through the array, the first m elements are in sorted order. Statement 2: And these elements are the m smallest elements in the array.

Detailed explanation-3: -Insertion Algorithms: Steps on how it works: Shift all the the elements in sorted sub-list that is greater than the value to be sorted. Insert the value. Repeat until list is sorted.

Detailed explanation-4: -Insertion Sort is a sorting algorithm where the array is sorted by taking one element at a time. The principle behind insertion sort is to take one element, iterate through the sorted array & find its correct position in the sorted array.
