Write the recurrence of the recursive case (not the base case) for mystery(n, 1) mystery(n, 1), where the initial value of the parameter step = 1 step = 1.
A) mystery(n-1, 1) + mystery(n-2, 1)
B) mystery(n-1, 1) * mystery(n-2, 1)
C) mystery(n-1, 1) - mystery(n-2, 1)
D) mystery(n-1, 1) / mystery(n-2, 1)
