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
