Explanation: Conducting an annual inspection of a GMDSS ship station involves more than just operating the equipment; it requires detailed knowledge of system functionality, maintenance procedures, and regulatory compliance. The GMDSS Maintainer's License (B) is specifically designed for individuals who install, maintain, and inspect GMDSS equipment. This license verifies the holder possesses the necessary technical expertise to ensure the system is operational and compliant with international and domestic regulations. A GMDSS Radio Operator's License (A) permits operation, not maintenance or inspection. The First Class Radiotelegraph Operator's License (C) and the General Radiotelephone Operator's License (D) are for different types of radio operations and maintenance, and do not specifically authorize GMDSS *inspections*.
