Which of the following is an example of a soft belay rope grab?

A soft belay rope grab is a device or method that allows for the effective control of a rope using friction, typically suited for dynamic situations in rescue scenarios. Tandem Prusiks exemplify this concept well because they consist of two Prusik knots that are used in conjunction to provide a gripping action on the rope. This configuration enables the rescuer to manage loaded lines effectively while allowing for easy adjustments and providing a safety backup, should one of the knots fail or slip.

The function of tandem Prusiks in a rescue setting allows for both descent and ascent scenarios, demonstrating their versatility as a soft belay device. They rely on the principles of friction and can be quickly disengaged when needed, making them suitable for situations where quick decision-making and response are critically important.
