Which HF SITOR mode would be selected to receive MSI broadcasts from high seas shore stations:

Correct Answer: Option B — FEC

Forward Error Correction (FEC) is the standard mode for receiving MSI broadcasts over HF NBDP (Narrow Band Direct Printing). Because MSI is a one-way broadcast to multiple ships, the ARQ (Automatic Repeat Request) mode is unsuitable, as it requires a two-way handshake between a single sender and receiver.
