What statement is true regarding Inmarsat-C?

Correct Answer: Option C — This is a store and forward network, with an intermediate step that means there is no direct connection between ship and shore users.

Inmarsat-C is fundamentally a store-and-forward system. Messages are transmitted from the ship to the satellite, then to a CES, where they are queued before being delivered to the terrestrial network. There is no direct, real-time circuit-switched connection between the ship and the shore-based recipient during the transmission.
