The following statement is an example of which type of opener? "You're the president of Key Club, aren't you?" self-references other references relational references context references

This statement is an example of other-reference, because the speaker addresses another person (you), thus, focusing on the listener.

It can't be an example of self-reference because the speaker doesn't refer to himself and it can't be a relational reference either because the speaker doesn't try to involve the listener in any way. It can't be a context reference either because it doesn't emphasize on the context, on the situation, but on the listener. A context reference isn't direct and personal like in this example.
