B) The recursion step executes while the original function call is still active (i.e., it has not finished executing) .
C) For the recursion to eventually terminate, each time the function calls itself with a simpler version of the original problem, the sequence of smaller and smaller problems must xe "converge on a base case"converge on a recursion step.
D) All of the above statements are true.
