Which RUDDER input prevents a stall from progressing to a SPIN?

Choices

Aggressive rudder in either direction.
Aggressive rudder causes yaw and triggers spin.
✓ COORDINATED (neutral or just enough to prevent yaw) rudder during the stall.correct
Coordinated rudder — neutral, or just enough to prevent yaw — keeps a stall from becoming a spin, because uncoordinated rudder is what creates asymmetric wing drag and starts autorotation. Spins require BOTH stall + yaw. Maintain rudder COORDINATION through stall recovery to prevent yaw. Use ball-centered as the indicator: if the ball isn't centered, you're sliding sideways and any wing drop will autorotate. Most spin entries occur when a wing drops at stall and the pilot uses opposite AILERON (which adds adverse yaw) instead of opposite RUDDER.
Full rudder opposite the desired turn.
Cross-control is the spin-entry recipe, not the prevention.
Rudder is not relevant to spin prevention.
Rudder coordination is THE key to spin prevention.
