Wind turbine blades begin turning at what wind speed and shut off at what wind speed or more?

Wind turbines are designed to start generating electricity when wind reaches the cut-in speed and to shut down at the cut-out speed to protect the equipment. For many turbines, the cut-in speed is about 9 mph, and the cut-out speed is around 60 mph, so they operate in between these values with controls adjusting blade pitch and generator load. This makes the option listing 9 mph to start and 60 mph to shut off the best match, because it aligns with the typical operating envelope used to balance production and safety. The other options set start or shut-off speeds outside the usual ranges, which would either reduce energy production or risk damage during very strong winds.
