Explanation: Programming authorized frequency channels into maritime service transmitters is a technical task requiring specific qualifications to ensure compliance with regulations and proper operation. According to FCC Part 80, Section §80.179(c)(1), this responsibility is restricted to persons holding a First or Second Class Radiotelegraph Operator's Certificate or a General Radiotelephone Operator's License. These specific licenses signify a higher level of technical expertise and understanding of radio theory and regulations. Therefore, answer D is correct because it accurately reflects the FCC's requirements for the specialized knowledge needed for programming, which goes beyond basic radio operation. Options A, B, and C describe insufficient qualifications or overly broad authorizations that do not meet these stringent regulatory standards. Restricted permits, for example, are typically for basic operational duties, not for technical modifications like programming frequencies.
