Solution

The main requirement for applying binary search is c. The array must be sorted in ascending order.

Here's why:

Binary search is a divide-and-conquer algorithm that works by repeatedly dividing the search interval in half. If the value of the search key is less than the item in the middle of the interval, the algorithm continues on the lower half. Otherwise, it continues on the upper half.

This process continues until the value is found or the interval is empty. For this reason, the array must be sorted in ascending order for the algorithm to work correctly. If the array is not sorted, the algorithm won't know which half to continue on and won't be able to find the desired value.
