K is an instance of the I class in the Python code below. Which of the following method calls either increment the value of the instance attribute or return the value of the class attribute? class I(): num = def init_(self): self.num =0 def method(self): return def methodA(self): I. num = def methodB (self): I.num = I.num +1 def methodC (self): self.num += 1 def methodD (cls): I.num = I.num + 1 methodD = classmethod (methodD) def methodE (cls): return I.num methodE = classmethod (methodE) def methodF (): return I.num methodF = staticmethod (methodF) def methodG (self): self.num = self.num +1 def methodH(self): self.num = I.num return self.num K.methodG() I.methodH () I.methodB () K.methodE () I.methodF ()
