Answer: Throw technique
Explanation:
Survival floating is a survival technique when it comes to swimming, reach technique is considering survival technique when someone is in a dangerous situation and they CAN reach something important to them at that moment(for example telephone), wearing helmets is also a good response in an emergency because it can save us(for examples if we are riding a bike).
