Patrick has recently received his registration as a mutual fund dealing representative, and is eager to get on the phones and start "cold calling" potential clients. To whom is Patrick permitted to make unsolicited telephone calls to market new products (i.e. cold calling) if they have registered on the national Do Not Call List (DNCL)?

1. A.Patrick may call someone who is not yet a client.
2. B.Patrick may call someone who used to be a client, but is not now.
3. C.Patrick may call someone with whom he already has a business relationship.
4. D.Patrick is not permitted to contact anyone on the DNCL for telemarketing purpose.
