Why super here in class A not calling the object class as super method is meant to call the parent class?

Question

class A:
    def method(self):
        print('a is running')
        super().method()

class B:
    def method(self):
        print('b is running')
        super().method()

class C:
    def method(self):
        print('c is running')
        
class X(A,B):
    def method(self):
        print('x is running')
        super().method()  

class Y(B,C):
    pass

class P(X,Y,C):
    def method(self):
        print('p is running')
        super().method()
print(P.mro())
g=P()
g.method()

Question 1:I understand the output from the MRO point of view but my question is since super is supposed to call the parent class so why class A is not calling the object class here?

Question 2: If I write super().method() in class C it gives me an error but instead of giving error shouldn't it search in the object class for method() and since there is no method() present in the object class, the search should stop there?

Question 3: If I use ' super().__init__() ' in class C , it doesn't give me any errors but why?
