Which automatic TELEX command should be sent by a ship station during SITOR operations to properly address a weather report to the national weather authority?

Correct Answer: Option B — OBS+

OBS+ is the standardized prefix for meteorological reports in SITOR/NBDP operations. This command alerts the shore-based station that the incoming data is a weather observation, ensuring it is routed correctly to the national meteorological authority for integration into global weather forecasting systems as required by WMO and IMO standards.
