Correct choice: "Charges within electric insulators do not readily move."
Explanation: In insulators (e.g., rubber, glass, ceramics) electrons are tightly bound to atoms, so they do not move freely and the material has very low electrical conductivity. Other statements are false or not generally true (insulators are usually poor electrical conductors; they are not defined by tensile strength; thermal conductivity varies).
