Can a passenger initiate an evacuation?

The correct choice regarding a passenger's ability to initiate an evacuation is based on the understanding of emergency protocols in aviation. Passengers are generally not authorized to initiate an evacuation unless they are specifically trained and are part of the crew. This is because safety procedures are designed to be managed by trained professionals who can assess the situation properly and lead the evacuation efficiently.

In the context of emergency exit rows, while passengers in those rows may have additional responsibilities such as assisting in evacuating others, they are still not granted the authority to initiate an evacuation independently. This is primarily to ensure that evacuations are conducted in a controlled manner, preventing chaos or unnecessary danger during an emergency situation.

Fundamentally, the process of evacuation should remain under the direction of the crew to ensure everyone's safety and the structured implementation of evacuation plans, which are critical during emergencies. The correct choice emphasizes that the crew members are the ones designated to make and implement these critical decisions during such scenarios.
