Final answer:
In balloon framing, the studs are continuous from the foundation to the roof line and are typically positioned 16 inches, or 40.64 centimeters, apart on center.
Step-by-step explanation:
In balloon framing, the correct answer is B. Continuous from foundation to the roof line. Unlike platform framing where studs run from the floor platform to the ceiling, in balloon framing, the studs extend in one continuous piece from the foundation sill all the way to the top plate of the second story.
The lumber used for the studs in balloon framing is typically 2-by-4 or 2-by-6 lumber, which can be 16 inches or sometimes 24 inches on center. When converted to centimeters, 16 inches is equal to approximately 40.64 centimeters.
