What is the nickname of the state of Ohio?

Ohio is commonly referred to as "The Buckeye State." This nickname comes from the abundant buckeye trees that are native to the region. The buckeye nut is a symbol of Ohio and is associated with the state’s identity. In addition to its botanical significance, the term "buckeye" also refers to residents of Ohio, who are often called "Buckeyes." The nickname reflects a sense of state pride and connection to local flora, as well as the tradition of carrying buckeye nuts as good luck charms.

Other options represent different states: "The Garden State" is known for New Jersey, "The Sunshine State" refers to Florida, and "The Keystone State" is a nickname for Pennsylvania. Each of these states has its own unique characteristics and cultural elements that lead to their respective nicknames, but they do not apply to Ohio.
