Which condition is a listed APU starting limitation related to airspeed?

Explanation:
APU starting limits are placed to ensure safe operation of the unit when air is flowing over the aircraft. Starting the APU at high airspeeds can disrupt the intake flow, make spool-up unstable, or cause unexpected surges due to ram air effects. The listed restriction—airstart is limited to speeds below 305 knots—means you should not attempt an APU start when you’re faster than that; you’d rely on ground power or another source instead, until you’re below the limit. The other options don’t match the documented speed-specific constraint, and saying there’s no airspeed limit would ignore this stated precaution.
