When we create a class and initiate a constructor....any defined variable inside this constructor will be an unique instance of any newly created object. Class A: def __init__(self, number): self.number = number return self.number # when we give A() an argument...such argument will be the instance created for the object b b = A(2) # when we give A() an argument...such argument will be the instance created for the object c c = A(3) # instance of object b is different from instance of object c Answer is D

A is correct =a. s.write ("Hello\n")
