Which states were the top three milk producers in 2012?

The top three milk producers in 2012 were California, Wisconsin, and Idaho. California consistently ranks as the largest producer of milk in the United States, thanks to its favorable climate and extensive dairy farming infrastructure. Wisconsin is often referred to as "America's Dairyland" and has a long history of dairy farming, particularly known for its cheese production. Idaho has emerged as a significant player in the dairy industry, with a growing number of large dairy operations contributing to its increased milk production.

The other options do not reflect the rankings of milk production accurately for that year. This knowledge is supported by agricultural reports and production statistics that highlight the impressive output from California, Wisconsin, and Idaho during that period, establishing their status as the leading states in milk production.
