Answer: fiduciary
Step-by-step explanation:
Since Maurice is a cautious investor and wants to make sure that any financial advice that he pays for is as free of conflicts of interest as possible, he should then seek out a financial advisor who provides advice and products based on a fiduciary standard.
The fiduciary standard simply states that the interest of the client should be out above the interest of the advisor and the advisor must follow the best course of action for the client regardless of how they're affected by this.
