Which action helps prevent unwanted drainage when filling cold water?

Explanation:
Stopping the fill with the Cold Water Fill Button is the best move because it halts incoming water exactly when needed, preventing overfill and the resulting drainage. When you press that button, you terminate the fill cycle so water doesn’t continue to flow and push out through the drainage path. If you leave controls alone, the system may keep filling and overflow, which leads to drainage. Opening the vent or opening a drain valve doesn’t stop the fill process itself and can cause other unintended effects, so they aren’t the correct action in this moment.
