In a land evacuation, which handle is pulled after opening the door in emergency mode?

The correct choice is the manual inflation handle. In a land evacuation scenario, after opening the emergency exit door, the manual inflation handle is used to deploy and inflate the slide, which provides a safe exit path for passengers exiting the aircraft. This step is critical to ensure that the slide is properly inflated and ready for evacuation.

In contrast, the emergency release handle is typically used before opening the door to allow the door to be operated in an emergency configuration. The slide disarm handle is used to deactivate the slide once it is no longer needed, ensuring it doesn't inflate inadvertently when the aircraft is not in an evacuation scenario. The evacuation handle is utilized to initiate the overall evacuation process, but it does not specifically pertain to the action of inflating the slide after the door is opened. Thus, the manual inflation handle is the key component in facilitating the safe and efficient evacuation of passengers in an emergency situation.
