The correct answer is: A. formal organization.
In a formal organization, authority flows from the top down. This means that the people at the top of the organization have the most authority, and the people at the bottom of the organization have the least authority. This type of organization is often used in businesses and government agencies.
An informal organization is a group of people who come together to achieve a common goal. There is no formal hierarchy in an informal organization, and authority does not flow from the top down. Instead, authority is shared among the members of the group.
A business organization is a type of formal organization that is created to make a profit. Business organizations are typically hierarchical, with a clear chain of command.
A strategic organization is a type of formal organization that is focused on achieving a specific goal. Strategic organizations are typically less hierarchical than business organizations, and they often have a more fluid structure.
In conclusion, the correct answer is: A. formal organization.
