What is the diameter range for light use rope?

Light use rope is typically defined within a specific diameter range that balances strength with weight and flexibility. The correct option indicates that light use ropes lie between 9.5 mm to 12.5 mm in diameter. This range is suitable for various technical rescue applications where the rope needs to be manageable and lightweight, yet strong enough to handle the demands of rescue scenarios without adding unnecessary bulk or weight.

Using ropes in this range ensures they have the appropriate tensile strength and durability for lighter applications, such as recreational climbing, caving, and some rescue practices. It is essential for rescuers to select rope within this diameter range to maintain efficiency and effectiveness during rescue operations.
