Define "dynamic rope" in the context of rope rescue.

In the context of rope rescue, a dynamic rope is specifically designed to stretch under load. This characteristic is crucial because it allows the rope to absorb energy from a fall, reducing the impact forces on both the climber and the anchors. The ability to stretch helps to enhance safety during rope rescue operations, particularly when dealing with potential falls or sudden loads. This elasticity is what differentiates dynamic ropes from static ropes, which are designed to have little to no stretch and are more suitable for applications where minimal movement is required.

Dynamic ropes are typically made from materials that provide appropriate strength while ensuring elasticity, making them ideal for climbing and rescue scenarios. The other choices, while they highlight certain attributes of ropes, do not capture the defining feature of dynamic ropes that is vital for their performance and safety in rescue situations.
