Correct Answer

Explanation

Bubble sort is a simple comparison-based sorting algorithm that repeatedly swaps adjacent elements if they are in the wrong order. In the worst case, where the array is reverse sorted, each pass of the algorithm requires traversing the entire array and potentially swapping adjacent elements. This results in a quadratic time complexity of O(n^2).
