Which tool would be ideal for working with high-tension cables?

Answer: B — High-voltage pliers

High-voltage pliers are specifically designed to safely handle high-tension cables. These tools have insulated grips and tips that protect the user from electrical shock, which is crucial when dealing with high-voltage or high-tension setups. The design ensures that the user maintains a safe distance from the current-carrying conductors while providing the necessary grip to manipulate and work with cables effectively. In contrast, the other tools listed lack the specific insulating features required for such dangerous work. Needle nose pliers are suitable for precision tasks but do not provide insulation for electrical work. Regular adjustable pliers do not have the necessary electrical safety features, making them unsuitable for high-tension applications. Wire cutters are intended for cutting wire but do not offer insulation protection, making them a poor choice for handling high-voltage scenarios. Thus, high-voltage pliers stand out as the safest and most appropriate tool for working with high-tension cables.
