Answer
Correct. Booker T defeated Jeff Jarrett on March 26, 2001, at WrestleMania X-Seven, to win the WCW World Heavyweight Championship. This marked the final time the title was defended under the WCW banner, as the promotion was purchased by the World Wrestling Federation (WWF, now WWE) in March 2001. The WCW World Heavyweight Championship was subsequently retired and replaced by the WWF Championship.
