This question requires a precise distinction between the RIBO Code of Conduct (Section 14) and the broader Ontario Regulation 991. While maintaining a Trust Account (Option A) is a fundamental legal requirement for all brokerages, it is technically governed by Section 16 of the Regulation, whereas Section 14 is dedicated specifically to the professional behavior and ethical standards of the individual member.

The RIBO Level 1 Blueprint emphasizes that Section 14 focuses on the "human" element of the profession: Integrity, Competence, and Candor. Provision 2 of the Code mandates that a member must be competent (Option D), Provision 4 requires being candid and honest (Option B), and Provision 5 prohibits undisclosed fees (Option C). These ethical pillars ensure that the relationship between the broker and the public is built on trust and transparency.

Understanding this distinction is vital for Legal and Regulatory Compliance. A broker must know that "Competence" means more than just passing an exam; it involves a continuous duty to serve the client in a conscientious and diligent manner. While the Principal Broker handles the administrative setup of the trust account, the individual Level 1 broker must adhere to the Section 14 standards in every interaction. By identifying that trust accounting is a separate regulatory duty from the Code of Conduct's ethical provisions, the broker demonstrates a sophisticated understanding of the RIB Act and its supporting regulations. This clarity is essential for Professionalism, as it helps the broker navigate the difference between "business operations" and "professional duty of care."
