Answer:

D ( All of the Above)

Explanation:

Since the array is sorted in ascending order and having found that the element at index 50 is 72, considering that 165 is greater than 72, it means that the following must be true

1) 165 can only be at a higher index (51-100)

2) The first half of the array (0-49) indexes can be ignored
