  2. Lead and Tin
  3. Aluminum and Nickel
  4. Iron and Chromium

Correct answer and explanation

Correct answer: Lead and Tin

Explanation: āœ… Correct Answer: B) Lead and Tin šŸ“š Explanation: A fuse wire is a safety device designed to melt and break the circuit if the current exceeds a safe limit. It is made from an alloy of lead and tin because this combination provides a low melting point and relatively high resistance. This ensures that the wire heats up and melts quickly during an electrical overload to prevent fire or damage.
