What algorithm would you use to arrange data in alphabetical order?

The correct choice for arranging data in alphabetical order is the bubble sort algorithm. This is a straightforward sorting technique that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. This process continues until no swaps are needed, which indicates that the list is sorted.

While bubble sort is easy to understand and implement, it is generally not the most efficient sorting method for larger datasets due to its average and worst-case time complexity of O(n²). However, it is important to recognize that for small sets of data or educational purposes, it demonstrates the concept of sorting effectively.

Other algorithms mentioned may also sort data but are optimized differently. For instance, merge sort and insertion sort offer better performance characteristics for sorted or almost-sorted data, while binary search is not a sorting algorithm; rather, it is a search method used to find elements in a sorted list.
