Which of the following best describes a choker hitch?

A choker hitch is characterized by its ability to tighten around the load as it is lifted, which is a key feature of this rigging method. When configured properly, as the load rises, the loop of the sling pulls tight, securing the load more firmly. This self-tightening nature enhances the stability of the load during lifting and transport.

Additionally, while it's true that some hitches are designed for vertical lifting or may have specific load characteristics, the defining element of a choker hitch is how it interacts with the load when tension is applied. The other considerations regarding the degree of pull or adjustment capability do not accurately capture the essence of a choker hitch. This hitch is primarily celebrated for its security and the snug fit it provides as lifting commences, making option B the most descriptive of its function.
