Discussion Board
WRONG

You do not inherit properties from an interface, you IMPLEMENT them. Implement, not inherit. Therefore, the question is wrong.

Bad choice of answers

Again, as stated above.

Options are bad

The answers given are not framed properly.

Question is broken indeed

Yeah, badly worded and 'create an interface object' is meaningless. Should probably be 'a' and 'b' if 'a' was 'implement the properties...'.

Question is broken

This question is either wrong or worded poorly. An instance of an interface can not be created/instantiated. Not is it possible to inherit an interface, interfaces are implemented. It doesn't even sound correct to say that the class uses an interface or that it contains the same methods. The interface does not contain methods, it contains method definitions.

what is "create an interface object"

what is "create an interface object" and why class must do it if the class is using an interface?
