What is a practical use for sodium?

Explanation:
Sodium is commonly used in glassmaking because sodium compounds act as a flux that lowers the melting point of silica, helping it flow and form smooth, workable glass. This key role of sodium oxide from soda ash is what makes glass a practical and important use for sodium. The other options don’t involve sodium in a direct, constructive way: artificial rubber relies on polymer chemistry and additives, table sugar is a carbohydrate, and copper wiring uses copper metal. So glass is the practical use for sodium among these choices.
