What characteristics describe an expandable baton?

An expandable baton is primarily characterized by its ability to extend and lock into place when force is applied. The typical design features a steel shaft that provides strength and durability, making it effective for self-defense or law enforcement purposes. The rigidity of the baton when deployed is crucial since it allows the user to apply significant force without the risk of bending or breaking, ensuring reliability in tense situations.

The color of the baton, often silver, is common for steel batons, which may have a polished finish. The combination of a steel shaft's strength and rigidity allows for a controlled, effective response when used as a defensive tool. This construction also supports the baton’s expandable nature, making it compact for easy storage while providing the necessary robustness when needed.

Other characteristics like the grip might vary, but the primary aspects of an expandable baton focus on material and functional design, helping it perform effectively under various conditions. This solid construction and functionality make option C the most accurate description of an expandable baton.
