Ugh, I hate these inheritance questions! But I think I've got this one. Since 'y' is protected in class A, it will be protected in class B too. The answer is C) protected.

This is a classic inheritance question. If 'y' is protected in class A, then it will be protected in class B as well. The answer is definitely C) protected.

Haha, this is a tricky one! I bet the professor is trying to trip us up. But if we remember the rules of inheritance, the answer has to be C) protected.

Yeah, I remember that from class. C) protected makes sense.

Yeah, I remember learning that protected variables are accessible by derived classes.

I think the correct answer is C) protected, as 'y' is accessible within the derived class B.

I believe the answer is C) protected, as 'y' is inherited from class A.

I agree with Queen, because class B inherits from class A.

Hmm, I'm not sure about this one. Since class B inherits publicly from class A, wouldn't 'y' be accessible in class B as well? I think the answer might be A) public.
