25) Which code calculates the power of a number raised to another (a^b)? O a. 0 0 0 0 0 0 0 0 def power (a, b) if b == 1: return a else: return a **power (a, b-1) O 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 O b. def power (a, b): if b == 1: return a else: return a power (b-1, a) C. def power(a,b):a" a" = a" if b == 1: return a else: return a * *power (b-1, a) d. :) def power (a, b) : if b === 1: return a n+m else: return a power (a, b-1)
