     - This is true. The control operator must be present at the control point to ensure proper operation and compliance with regulations.
   
   - **B: A control operator is required at all times**
     - This is also true. The control operator must be continuously available to manage the station, ensuring that it operates within the legal parameters and can respond to any issues that arise.
