Option E seems a bit odd - an abstract non-sealed class? That's a bit of a contradiction, isn't it?

I'd go with option F. Making the class final ensures that it can't be extended, which might be the intended behavior here.

Option B looks good to me. A simple public class that extends the Doc class in the p1 package.

I disagree, I believe option D is correct because it uses the 'sealed' keyword.

I think option A is valid because it extends the Doc class.
