Which of the following defines the rules governing the internal management of the commission?

The correct answer is C, as bylaws specifically refer to the rules and regulations that govern the internal management and operations of an organization, such as a commission. Bylaws typically outline the procedures for meetings, decision-making processes, roles and responsibilities of members, as well as the structure of governance.

In the context of a commission, having clear bylaws helps ensure that all members understand the framework within which they are to operate, leading to more efficient and effective management. Bylaws serve as a foundational element for the organization's governance, thereby providing clarity and stability.

The other options, such as disbursements, are related to financial transactions and management rather than internal rules. Civil action pertains to legal proceedings and does not address internal governance. The majority of legislatures refers to a political concept concerning decision-making within legislative bodies, which is outside the scope of internal management for a commission. Thus, bylaws are the most appropriate term that encapsulates the established rules for managing the commission internally.
