- ABoth bedrooms meet their individual specified allocations.

- DThe measured total is 70 cfm.
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why B is correct
The combined flow is 60 cfm in both cases, but distribution differs. Bedroom 2 receives 30 rather than 35 cfm. A correct total does not prove each room meets its supplied design allocation.
