Answer 1

Answer:

The answer is (b). 1.

Explanation:

In the code there is only 1 base case .

the base case is as following:-

if(n==0)

return 0;

Base case is the most important statement in the function that uses recursion because without base case the recursion calls will keep on going and we will get a run time error.
