Which risk increases when an aircraft's skin exceeds a Reynolds number threshold?

💡 Explanation

A higher Reynolds number indicates increased inertial forces in the boundary layer, thus promoting transition to turbulence. This transition increases drag because turbulent flow has higher friction than laminar flow; therefore, option C; rather than accelerated corrosion or acoustic resonance, which depend on other mechanisms.
