The correct answer is based on the specific functionality and effectiveness of the devices mentioned in relation to tensioning a static line. A ratchet and pawl mechanism is designed to allow for precision in adjusting tension, which is crucial in securing scaffolding and ensuring safety during use. The ratchet can lock into place, preventing any unintended slack, while the pawl ensures that it cannot slip back once the desired tension is achieved.

The rated turnbuckle with locking nuts further enhances this process, as turnbuckles are specifically designed to adjust the tension in cables or ropes. They work by twisting the body to either tighten or loosen, and when combined with locking nuts, they provide a secure hold that minimizes the risk of slippage or loosening over time. This combination of devices ensures that the static line remains securely tensioned, which is critical in scaffolding applications where stability and safety are paramount.

In contrast, while other choices may include devices that could potentially provide some form of tensioning, they do not offer the same level of reliability or effectiveness as the ratchet and pawl with a rated turnbuckle with locking nuts. Devices such as hooks and loops or wire and chain do not specifically provide tensioning capabilities, and spring devices may not adequately maintain
