Which of the following is true regarding the Board?

The assertion that the Board provides advice regarding trust accounting rules is valid and reflects an important aspect of its function. In the realm of real estate, proper handling of trust accounts is crucial for protecting clients' funds. The Board, typically a regulatory body for real estate, ensures that agents and brokers adhere to these accounting practices, as failure to do so can lead to legal repercussions and loss of trust.

Trust accounting rules govern how client funds must be managed, ensuring transparency and accountability. By providing guidance on these rules, the Board plays an essential role in maintaining ethical standards within the real estate profession. This function is vital for fostering trust between the agent, the clients, and the financial systems implemented in real estate transactions.

Other options may not accurately reflect the Board's roles: investigating commission disputes typically falls under different regulatory or legal proceedings, being comprised solely of real estate agents does not acknowledge the inclusion of diverse professionals in regulatory boards, and while licensing brokers and salespeople is a common function of a Board in many jurisdictions, the specific phrasing in other options could mislead regarding the primary focus of the Board. Thus, option C is noted for highlighting a foundational aspect of the Board's advisory capabilities in trust accounting.
