      self.__count=count
a=Count(2)
b=Count(2)

c= ''hello''
d= ''hello''
print(id(c)==id(d))

Answer : B

Explanation

The objects with same contents share the same object in the python library but this is not true for custom-defined immutable classes.

class B(A): 
   def __init__(self,j=0): 
      self.j=j 
def main():
