A line organization is a traditional and straightforward organizational structure characterized by a clear, unbroken chain of command. In this structure, authority and responsibility are clearly defined at each level, ensuring that every employee knows who their direct superior is.

• A: From bottom to top is contrary to the hierarchical nature of authority in most organizations.
• B: Horizontally between departments describes coordination or communication, not the primary flow of authority in a pure line structure.
• D: In a circular manner is not a recognized or practical flow of authority in organizational structures.
