Why is the correct selection of the LES in the Distress Alert Setup menu so crucial?

A.
Each LES has its own dedicated RCC whose jurisdiction is defined by the LES selected.
Correct Answer
B.
The LES choice determines the nationality of the RCC which will handle the Distress traffic and perform SAR duties or that will pass the particulars to the RCC with jurisdiction to coordinate the SAR situation.
C.
Inmarsat terminals use the GPS position to automatically determine the optimum LES choice in a Distress situation.
D.
The vessel need not select the LES because the NCS will always intercept a Distress priority call and route it to the closest RCC.
