What will be the output of the following code snippet?

class A:

def $\_\_$init$\_\_($self$)$:

self.calcI$(30)$

def calcI$($self$,$ i$)$:

self.i $=2*$ i;

class B$($A$)$:

def $\_\_$init$\_\_($self$)$:

super$().\_\_$init$\_\_()$

print$("$i from B is$",$ self.i$)$

def calcI$($self$,$ i$)$:

self.i $=3*$ i;

b $=$ B$()$

Question $12$ options:

The $\_\_$init$\_\_$ method of only class B gets invoked.

The $\_\_$init$\_\_$ method of class A gets invoked and it displays $$i from B is $0.$

The $\_\_$init$\_\_$ method of class A gets invoked and it displays $$i from B is $60.$

The $\_\_$init$\_\_$ method of class A gets invoked and it displays $$i from B is $90.$
