C. For purposes of this section, if any return, claim, statement, or other document or payment is sent by United States registered mail, the registration shall be prima facie evidence that the return, claim, statement, or other document or payment was delivered to the county assessor to which addressed, and the date of registration shall be deemed the postmark date.

D. The provisions of this section shall not apply with respect to returns, claims, statements or other documents or payments which are required under any provision of the Ad Valorem Tax Code to be delivered by any method other than by mailing.
