What is the correct affiliation of Notre Dame in college basketball?

Notre Dame is affiliated with the Atlantic Coast Conference (ACC) in college basketball. This affiliation is significant because it connects Notre Dame with a range of competitive programs and enhances its visibility and opportunities in the sport. The ACC is known for its strong basketball tradition and successful programs, which have historically performed well in national tournaments. The decision for Notre Dame to join the ACC was driven by several factors, including a desire for a more competitive environment and the ability to strengthen rivalries with other prominent programs.

The other conference affiliations listed were relevant at different times in history but do not reflect Notre Dame's current status. The Big East was Notre Dame's former conference before the shift to the ACC, while Mountain West and Atlantic 10 are separate conferences that Notre Dame has never been affiliated with in basketball. Understanding Notre Dame's current affiliation with the ACC is important for following their performance and competition in college basketball today.
