C Correct answer
Explanation

Silver is the best natural conductor of electricity among all elements - even better than copper and gold. This is why it's used in high-performance electrical contacts and specialized applications. Glass, ebonite, and rubber are all insulators - they have very high electrical resistance and do not allow current to flow through them easily. Ebonite is specifically a hardened rubber designed to be an excellent insulator.
