Alright, let's think this through. We need the class to be closeable, and we need to actually have a close() method. A and D it is!

Haha, I bet the exam writer had a good laugh throwing in that Folder extends Exception option. That's just cruel.

I'm not sure why C is even an option. Extending Exception? That seems completely off-base for this question.

Hmm, that makes sense. So, we need to implement AutoCloseable and add the close method with IOException to achieve the desired output.

I disagree, I believe option E is the correct choice because it adds the close method with IOException which is necessary for proper closing of resources.

Luisa

I think option A is correct because implementing AutoCloseable allows for the close method to be called automatically.

A and D seem like the obvious choices here. Implementing AutoCloseable and adding a close() method should do the trick.
