Option A => cannot be used to search an array that is not sorted
Explanation:
The reason for choosing ‘option a’ is that, the actual working mechanism of binary search is to sort the array first then choose a middle element and compare the given search element with the help of middle element. Let us deeply understand how this sorting and choosing middle element does the work of search.
So this middle element is the key pointer which tells the system that the matching element might be present either to the list of values which are less than middle element or it would be present in the right side / greater than middle element. So, it would search only in the list satisfying the middle element. So it is always necessary to sort the element.
