Some tribes approve of certain Native American mascots. What evidence in the text supports this claim?

a. "Before every home football game at Florida State University, a student portraying the famous Seminole leader Chief Osceola gallops down the field on the back of an Appaloosa horse named Renegade."
b. "The National Collegiate Athletic Association (NCAA)—the organization that regulates college sports—has banned the use of Native American logos and mascots during its postseason tournaments since 2006."
c. "Both the Seminole Tribe of Florida and the Seminole Nation of Oklahoma said they liked FSU's nickname, forcing the NCAA to rethink its stance against mascots—at least as far as the Seminoles were concerned."
d. "'Oftentimes, when a video camera is panning an audience at a football game, we see a young person with [a painted] face wearing a huge headdress,' Steve Densen, a member of the Chickasaw Tribe, told Senior Edition."
