My primary concern would be the safety and well-being of the passengers on the bus.
In such a scenario, the best course of action would be to stay calm, not provoke the hijacker, and comply with their demands to avoid escalating the situation. It would be essential for everyone to remain as quiet and non-confrontational as possible to prevent any harm.
The most appropriate response would be to prioritize the safety of the passengers and cooperate with any instructions given by the hijacker. Once the authorities are alerted, they can handle the situation and work towards a peaceful resolution. It is crucial to remember that in emergency situations like this, the safety and security of human lives take precedence above all else.
