Which of the following statements about the state of California's stance on real estate ethics is true?

While California does have a Business and Professions Code that outlines ethical standards for real estate agents, this is not considered an official code of ethics. Option A is incorrect because it suggests that California has a separate, official code of ethics for real estate. Option B is incorrect because while California may adopt the National Association of Realtors code, this is not considered the official code for the state. Option C is incorrect because while California may recommend following federal guidelines, this is not the same as having an official code of ethics in place. Therefore, the only accurate statement is that California has no official code of real estate ethics.
