What is the output of the following code?

from abc import ABC, abstractmethod

class A(ABC):

    @classmethod

    @abstractmethod

    def m1(self):

        print('In class A, Method m1.')

class B(A):

    @classmethod

    def m1(self):

        print('In class B, Method m1.')

b = B()

b.m1()

B.m1()

A.m1()

 
a. In class B, Method m1.
In class B, Method m1.
In class A, Method m1.
