Diamond

Gold

Silver

Graphite

✅ Correct Option: 1

Conductors → allow electricity to flow, e.g. metals like Gold, Silver.

These are good conductors of electricity.

Insulators → block electricity, e.g. non-metals like Diamond.

Diamond is a bad conductor of electricity.

Graphite → is a special case, it's a non-metal but → conducts electricity.

So, it's not the answer we're looking for.

Answer: Diamond, as it's a bad conductor of electricity → doesn't allow electricity to flow.

Option 1: Diamond is the correct answer.
