Which one of these universities is not part of the Big Ten Conference?

The University of Utah is not part of the Big Ten Conference. Instead, it is a member of the Pac-12 Conference. The Big Ten Conference is one of the oldest and most prestigious collegiate athletic conferences in the United States, consisting of 14 member institutions primarily located in the Midwest and Northeastern regions of the country.

Ohio State University, Penn State University, and the University of Maryland are all established members of the Big Ten. Ohio State is renowned for its strong athletic programs, particularly in football, while Penn State has a storied history in both athletics and academics. The University of Maryland joined the Big Ten in 2014, expanding the conference's presence on the East Coast.

The inclusion of the University of Utah in this question underscores the distinction between different athletic conferences, emphasizing the importance of knowing the affiliations of various universities within collegiate athletics.
