In which area do Boards of Inquiry have authority?

Boards of Inquiry possess authority primarily in geographical areas. This is because their role is to address and resolve issues related to local or regional golf operations, ensuring that rules and regulations are upheld within specific jurisdictions. They focus on incidents that occur within their designated regions, which allows them to make informed decisions based on the context and circumstances of local events.

While each of the other options relates to various aspects of the golfing community, they don't specifically align with the purview of a Board of Inquiry. For example, national tournaments are usually governed by overarching bodies that set the rules at that level, rather than by a localized Board of Inquiry. Similarly, national offices handle administrative tasks and policies at a broader level than what is typically addressed by a Board of Inquiry. The term "All Sections" suggests a comprehensive oversight that transcends the localized authority specific to Boards of Inquiry, which is why this option is not the correct focus for their authority.
