Show answer & explanation
Correct answer: C
The given array [23, 32, 45, 69, 72, 73, 89, 97] is already sorted in ascending order. Insertion Sort has a time complexity of O(n) for nearly sorted or already sorted arrays, making it the most efficient choice among standard sorting algorithms in this specific case.
