I was not 100% sure of my answer, but I picked the one that was not capitalized likt the others. And I have never seen a data type with an underscore in it before.
The sql_variant data type was introduced in SQL Server 2000. Interesting data type but I've not had a use for it yet myself.

I did some research on it. I have learned more from the questions on this site than most anywhere else. Keep up the good questions.
