Given an unsorted array. The array has this property that every element in the array is at most k distance from its position in a sorted array where k is a positive integer smaller than the size of an array. Which sorting algorithm can be easily modified for sorting this array and what is the obtainable time complexity? $(7)$a$)$ Insertion Sort with time complexity O$($kn$)$b$)$ Heap Sort with time complexity O$($nLogk$)$c$)$ Quick Sort with time complexity O$($kLogk$)$d$)$ Merge Sort with time complexity O$($kLogk$)$
