Detailed Explanation
Answer: (B) Recursive function
A function that calls itself is called a recursive function.
In the given example, factorial() calls itself using factorial(n - 1).
A recursive function normally requires a base condition to stop further recursive calls. Here, n <= 1 acts as the base condition.
