Which of these schools has a rivalry with Virginia?

Virginia has a well-established rivalry with several schools, but the most prominent among the choices provided is indeed Clemson. This rivalry is significant due to both schools' participation in the Atlantic Coast Conference (ACC) and the competitive nature of their encounters, particularly in football and basketball. The games between Virginia and Clemson often carry a lot of weight in the standings, which intensifies the rivalry. Additionally, both schools have had successful seasons in recent years, further heightening the competitive spirit during matchups.

The other options, while they may have some form of competitiveness with Virginia in different contexts, do not have the same level of historical significance or intensity as the Virginia-Clemson rivalry, especially in the landscape of ACC sports.
