Which statement best describes airbelts by model according to the material?

• A. All BC seats on all models have airbelts.
• B. On the 777-200ER only bulkhead BC seats have airbelts.
• C. All BC seats on the 777-300ER have airbelts.
• D. No BC seats have airbelts on any model.

Answer: (B)

Airbelts are not universal; the material describes them as model- and seat-position specific. Specifically, on the 777-200ER, airbelts are installed only on the bulkhead seats in the BC pair. This precise mapping makes the statement the best fit because it matches exactly what the material states: the 777-200ER has airbelts only for bulkhead BC seats. Other options overgeneralize (all BC seats have airbelts or all BC seats on the 777-300ER do) or claim none exist, which the material does not support.
