Solution

The correct statement is: The best-case time complexity of linear search is O(1) and binary search is O(1).

Here's why:

  1. Linear Search: In the best-case scenario, the element to be searched may be found at the first position. So, only one comparison is needed. Hence, the best-case time complexity of linear search is O(1).

  2. Binary Search: In the best-case scenario, the element to be searched is the middle element of the sorted array. So, only one comparison is needed. Hence, the best-case time complexity of binary search is also O(1).
