C. Charges within electric insulators do not readily move.

Explanation: Insulators (e.g., rubber, glass, plastic) do not allow free movement of electric charges, so they resist electrical current. The other options are incorrect: insulators are typically poor electrical (and often good thermal) conductors, and charge does not move freely in them.
