Copper metal is used in making:
Copper metal is used in making:
- A. electric wires
- B. fuse wires
- C. filling cavity in teeth
- D. preparation of hydrogen
Step-by-step solution
Copper is an excellent conductor of electricity due to its low resistivity, making it ideal for electric wires. Options B, C, and D are incorrect: fuse wires typically use tin-lead alloys, cavity fillings use dental amalgam (mercury alloy), and hydrogen preparation usually involves active metals like zinc or acids.
