What question should you keep in mind when debugging a recursive method
a. is there at least one recursive call
b. did u consider all possible cases
c. all other answers
d. does the method contain a statement to test an input value and leads to different cases?

A. Is there at least one recursive call

Explanation:

While debugging a recursive method we should always check that the method contains atleast one recursive call or not. If the method contains no recursive calls then the method is not a recursive method.Recursive call is most important part of the recursive solution.

Recursion is when the function call itself in the function .
