C Correct answer
Explanation

The red radial line on an airspeed indicator marks the never-exceed speed (Vne), which is the maximum speed the aircraft structure can withstand. Exceeding this speed, even momentarily, risks catastrophic structural failure. Vne is determined during flight testing and includes a safety margin below the actual speed at which the aircraft would break apart.
