Which line of code will use the overloaded addition operation? class num:
def __init__(self, a):
self. number = a

def __add__(self, b):
return self. number + 2 * b. number

def __mul__(self, b):
return self. number + b. number

def __pow__(self, b):
return self. number + b. number

# main program

numA = num(5)
numB = num(10)

1)result. add(numA, numB)
2)result = numA + numB
3)result = numA. add(numB)
