What is the length and type of rope used for the truck?

The correct choice, which specifies a length of 300 feet and a diameter of 1/2 inch, relates to the preferred specifications for safety and usability in various truck-related operations. The kernmantle construction of the rope is particularly important because it consists of a strong inner core (the kern) and a protective outer layer (the mantle). This design offers excellent strength and durability while also providing added resistance to abrasion and environmental factors.

Additionally, the designation of the rope as a "static life safety rope" indicates that it is specifically engineered for situations where minimal stretch is essential. In emergency or rescue scenarios, static ropes provide the reliability needed to ensure safety when carrying loads or during operations that require secure anchoring.

The other options provide different lengths or types of rope that may not align with the specific requirements for safety operations in truck usage. For instance, lengths longer than specified can create complications in handling, while different types or insufficient diameters might not provide the same level of safety assurance necessary for critical applications.
