A rope with minimal stretch under load is:

A rope with minimal stretch under load is categorized as static. Static ropes are specifically designed to maintain their length when weight is applied, making them ideal for applications such as rescue operations, rappelling, and anchoring, where a predictable and stable length is crucial for safety and performance. This characteristic allows firefighters and rescue personnel to work with confidence, knowing that the rope will not elongate significantly under load, which could otherwise lead to unpredictable situations or falls.

In contrast, dynamic ropes are engineered to stretch under load, absorbing energy during falls, which is advantageous in climbing situations but less suitable for rescue operations. Fixed and pliant do not accurately describe the stretch characteristics of a rope under load, as fixed generally refers to a state of being secured without movement, and pliant suggests flexibility, which does not pertain to the minimal stretch characteristic being described in this context.
