If programming a class to represent a calculator, which class containing methods with parameters could be used to multiply and divide input values x and y, and increment the total number of calculations performed? a.)class Calc: def __init__(self): self.numOfCalcs = 0 def mult(self): self.numOfCalcs +=1 return x * y def div(self): self.numOfCalcs +=1 return x / y b.)class Calc: def __init__(self): self.numOfCalcs = 0 def mult(self): numOfCalcs +=1 return x * y def div(self): numOfCalcs += 1 return x / y c.)class Calc: def __init__(self): self.numOfCalcs = 0 def mult(self,x,y): numOfCalcs +=1 return x * y def div(self,x,y): numOfCalcs += 1 return x / y d.)class Calc: def __init__(self): self.numOfCalcs = 0 def mult(self,x,y): self.numOfCalcs +=1 return x * y def div(self,x,y): self.numOfCalcs += 1 return x / y
