Hey there! 

The answer to your question is c) Stay calm and keep all involved calm. 
Whenever there is any emergency situation, keeping yourself and others calm is usually the best thing to do to stop the panic. 

Thank you!
Stay calm , establish control of scene(keep others calm, designate someone to call 911,etc and then attempt First Aid or CPR as necessary.
