formal region.

To determine the correct answer, we need to understand the definitions of each option and consider the characteristics of the Corn Belt.

1. County: A county refers to a territorial and administrative division within a state or country. It is typically smaller in scale, focusing on local governance.

2. Formal Region: A formal region is a recognized area defined by certain physical, cultural, or administrative traits that are present throughout the region. These characteristics are typically measurable and consistent.

3. Perceptual Region: A perceptual region, also known as a vernacular region, is a region that exists in people's minds based on their perceptions, opinions, and cultural biases. It does not have clearly defined boundaries.

4. Functional Region: A functional region is an area organized around a central focal point or a specific function, such as a city or economic activity. It consists of a central location and the surrounding areas that rely on it for certain services or resources.

Based on these definitions, the answer is most likely "formal region." The Corn Belt refers to a region in the United States that is known for its high agricultural productivity, specifically for corn farming. This region spans across several states in the Midwest, including Iowa, Illinois, Indiana, Nebraska, and others. It is recognized for its consistent characteristics, such as its climate, soil, and agricultural practices, which contribute to a high yield of corn production. These factors make the Corn Belt a formal region, as it has physical and agricultural traits that are measurable and consistent throughout the defined area.
