Differences Between Flying Boats and Floatplanes

Contrary to a floatplane, a flying boat touches the water with its fuselage or body. Since this fuselage is essentially a large, hollow hull, it allows for stability even when the sea is rough (with the help of two small floats underneath the wings). On the other hand, a floatplane floats thanks to its two pontoons or long floats. Its body doesn't touch the water.

This difference is highlighted in the text as one of the key distinctions between flying boats and floatplanes. Flying boats have a hull that enables them to float, while floatplanes rely on pontoons for flotation.

Therefore, based on the information provided, the correct answer to the question is B) A flying boat floats on its fuselage.
