What helps to determine the number of members on the Board of Natural Resources?

The correct answer reflects the stipulations laid out in the Georgia Constitution regarding the organization of the Board of Natural Resources. Specifically, the structure is designed to ensure equitable representation across the state's counties while also incorporating broader representation from the state at large. This structure aims to balance local interests with statewide concerns when it comes to natural resource management.

By designating one member for each county, plus an additional five members selected from the state at large, the Board is able to effectively represent diverse geographical and local interests which is essential for addressing the unique environmental concerns and resource management challenges faced across different regions of Georgia. This setup allows for a comprehensive approach in policy-making that considers both rural and urban perspectives.

The other options do not align with the mandated composition of the Board, as they propose a level of representation that could neglect the interests of numerous counties or regions, potentially leading to an unbalanced approach to natural resource management in the state.
