Final answer:
The administrator may require a Financial Consulting Advisor to register with the SEC if they transact business with six or more retail clients in any state. This is to ensure regulatory compliance and investor protection. Other requirements like submitting annual reports or providing proof of insurance may also apply.
Step-by-step explanation:
The question pertains to a regulatory requirement for Financial Consulting Advisors (FCA) concerning transactions with retail clients in various states. The correct answer is: A) Register with the SEC. This is because the Securities and Exchange Commission (SEC) requires certain advisors to register with them, particularly when they transact with a larger number of retail clients across different states. Registering with the SEC ensures that the FCA adheres to the regulations and compliance standards set forth for the protection of investors. The requirement of annual financial reports, proof of insurance coverage, and notifying the IRS of their activities may also be applicable depending on various regulatory frameworks but, based on the specific mention of transactions with six or more retail clients, registration with the SEC is the most relevant action described here.
