Correct answer
C. A sudden change in wind speed or direction over a short distance that can upset an aircraft
Why
Wind shear can occur near thunderstorms, fronts, and inversions, and it can overwhelm a small drone's climb and control margins. Unexpected drift or power demand at low altitude can be an early sign.
