What characteristic defines the Georgia executive branch in terms of its structure?

The defining characteristic of the Georgia executive branch is that it includes multiple agencies supervised by the Governor. This structure allows for a division of responsibilities and functions within the executive branch, enabling more efficient governance. Each agency is responsible for specific areas ranging from education to transportation, effectively allowing the Governor to manage the state's affairs comprehensively. By overseeing these agencies, the Governor ensures that policies and laws are implemented effectively across various sectors of state government. This feature highlights the complexity and organizational depth within the executive branch of Georgia, which is designed to cater to the diverse needs of its citizens.

The other options do not accurately reflect the structure of Georgia's executive branch. For instance, reliance on federal guidelines does not define the branch's structure; rather, it indicates a relationship between state and federal governance. Saying it consists solely of the Governor neglects the critical role that various agencies play in the functioning of the executive branch. Describing it as governed by a board of directors misrepresents the leadership model in Georgia, which is centered around an elected Governor rather than a board setup.
