Answer:
C. You can follow the customer's written instructions and hold the mail for an additional 3 months if the letter included an acceptable reason for holding the mail
Explanation:
Only if the customer requests in writing, FINRA will not authorize the mail of a customer to be kept. No further information is required as long as the application does not extend 3 months.
If, furthermore, the customer requests the mail kept for more than 3 months, then perhaps a genuine reason, like health or safety issues, should be included in the order.
FINRA aggregates all hold requests which occur during one year in calculating the 3 months. The first proposal to hold for 2 months did not require an acceptable reason.
The next application involves the client in 1 year over 3 months, so a valid excuse should be provided in the letter of 2nd request to keep the mail of that customer again.
