Explanation: FCC regulations assign responsibility for proper station operation and record-keeping to multiple parties. The **station licensee** holds the ultimate legal responsibility for ensuring their station complies with all FCC rules, including the proper maintenance of station logs. This is an inherent part of holding the station license. However, the **radio operator in charge of the station** (known as the control operator in amateur radio) is directly responsible for the proper operation of the station at the time of use and for accurately logging all required entries during their operating period. They are accountable for their actions and the immediate record-keeping. Therefore, both parties share responsibility: the licensee for overall compliance, and the operator for specific operational logging. Options A is incomplete as it misses the operator's direct responsibility. Options B and C introduce specific commercial or maritime contexts which are not universally applicable to all radio stations, unlike the more general responsibility shared between the licensee and the operator in charge.
