Question
**Binary Search Exercise**

Given the array below and the target \( k = 6 \):

\[ A = [2, 6, 17, 19, 21, 41, 51, 57, 82, 91] \]

**Question:**  
Which numbers will binary search compare the target to on its way to finding the target number?

**Options:**

- ○ 21, 6
- ○ 41, 17, 6
- ○ 41, 17, 2, 6
- ○ 21, 17, 6

**Explanation:**

Binary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing the portion of the list that could contain the target number in half until you've narrowed the location to just one possibility.

**Note:** Choose the correct sequence of numbers that binary search will compare the target \( k = 6 \) to in order to find it in the array.
