Which statement correctly pairs two INMARSAT systems listed in the material?

• A. INMARSAT B and INMARSAT C
• B. INMARSAT A and INMARSAT D
• C. INMARSAT X and INMARSAT Y
• D. INMARSAT M and INMARSAT G

Answer: (A)

The main idea here is recognizing how INMARSAT systems are organized by generation and family, so the material groups related systems together as a pair. INMARSAT B and INMARSAT C are presented as a matched duo because they belong to the same early-generation family and share the same general context of maritime communications, making them the natural pairing in the source. This pairing reflects how these legacy systems were developed and used together, highlighting their compatibility or complementary roles within the same era. The other options mix systems that the material does not pair together in the same way, either because they belong to different generations or kingdoms of service, or because such a pairing isn’t how the material organizes the listings. This is why that pair isn’t chosen, and why the B and C pairing stands out as the correct match.
