The condition for the recursive call is n > 0 and the method is called with n+1. Since 10 is passed as an argument initially, the first call will have n=10, the second call will have n=11 (since n+1 is passed), the third call will have n=12, and so on. This will continue infinitely as there is no condition to stop the recursion. Therefore, the answer is D, an infinite number of times.
