Which city is home to the Michigan State University?

Lansing is the correct answer because it is the location of Michigan State University (MSU), which is one of the largest and most prestigious public universities in the United States. The university was founded in 1855 and plays a significant role in the city's identity and economy. MSU's campus is known for its extensive research programs, beautiful landscapes, and a large student population, contributing to the culture and vibrancy of Lansing.

The other cities listed do not serve as the home of Michigan State University. Flint is known for its automobile history and recent revitalization efforts. Ann Arbor is the location of the University of Michigan, a prominent rival institution. Grand Rapids is recognized for its art scene and as a hub for health care and manufacturing, but it is not affiliated with MSU.
