Are we sure B is the best option? What about A?

Wait, why would you need 'val' in D? Seems off.

C makes no sense, it won't access the instance method.

I’m confused about D since it has an extra parameter. I don't think we need to pass anything to get(), so that seems wrong.

I practiced a similar question, and I feel like print(self.get()) is the standard way to call a method in Python, so I'm leaning towards B.

I'm not entirely sure, but I remember something about needing to call the method on the instance, so maybe A could work too?

I think the answer might be B because it uses self, which is how we usually access instance methods.

I'm not entirely sure about this one. The wording of the question is a bit tricky, and I'm not 100% confident in my understanding of how instance methods work in this context. I'll need to review my notes on class definitions and method invocation before I can give a definitive answer.

Okay, I think I've got it. The key here is that the question wants us to use the "show()" method to invoke the "get()" method and output the result. Since "get()" is an instance method, we need to call it on the self object, so the answer is B - print(self.get()).

Hmm, I'm a bit confused here. The question mentions invoking the get() method, but it doesn't specify where that method is defined. Is it a method of the class in the image, or is it a separate function? I'll need to think this through carefully before answering.

This looks like a pretty straightforward question. I think the answer is B - print(self.get()). The question states that we want the show() method to invoke the get() method, and then output the value it returns. Since get() is an instance method, we need to call it on the self object.

Hmm, this is a tricky one. But I think B) print(self.get()) is the right answer. Gotta love those self-referential method calls!

B) print(self.get()) is the way to go. I mean, come on, it's basic object-oriented programming 101.

Definitely B) print(self.get()). The 'self' keyword is used to refer to the instance of the class, so that's the way to access the get() method.

No, A) print(get(self)) would not work because get() is a method of the object, so we need to use self.get().
