Which statement about the 787-9's 3-tiered carts compared to the 787-8 is correct?

• A. The 787-9 has 0 carts
• B. The 787-9 has 1 cart
• C. The 787-9 has 2 carts
• D. The 787-9 has 3 carts

Answer: (B)

The key idea here is how galley equipment is tailored to each aircraft variant’s layout and service flow. For the 787-9, the forward galley configuration includes a single 3-tiered cart to maximize service capacity in the longer cabin. The 787-8, being a shorter version, does not require this extra tier and uses standard carts instead, so it does not have a 3-tiered cart. That’s why the correct statement is that the 787-9 has one 3-tiered cart. The other counts would not match the actual galley setup on these models.
