Answer: C. The arrangement is permitted only if it is in writing between the investment adviser and the friend and the arrangement is disclosed in writing to any customer opening an account
Step-by-step explanation:
The friend in this case will be ruled to be a Solicitor under SEC Rules as they are referring clients to the Investment Adviser for a fee.
As such this business relationship between the friend and the Investment Adviser representative will fall under SEC Rule 206(4)-3 Cash payments for client solicitations. This rule makes it clear amongst other things that the investment adviser will have to prepare a written disclosure document which will inform any customer opening an account of the agreement between the adviser and his friend.
