The array is as follows: 1,2,3,6,8,10. At what time the element 6 is found?…

Answer: a

Explanation: In recursive linear search, the function starts from the first element (index 0) and makes a recursive call for each element until the target is found. The array is 1, 2, 3, 6, 8, 10. The element 6 is at index 3 (0-based). The first call checks index 0, second checks index 1, third checks index 2, and fourth checks index 3. Thus, the element is found in the 4th call.
