A, B, D, E.
The ___ can be filled with any class or interface that is a supertype of RoundRectangle.
A is a superclass of RoundRectangle, and B is the same class, so both are correct.
RedRoundRectangle is not a superclass of RoundRectangle, so C is incorrect.
RoundRectangle inherits the Printable interface, so D is correct.
All classes inherit Object, so E is correct.
Long is an unrelated class that is not a superclass of RoundRectangle, and is therefore incorrect.
