Concept:A fuse wire protects circuits by melting when current exceeds a safe limit.
So it must be conducting to carry normal current and have a low melting point to break the circuit quickly.
Explanation:The fuse wire is placed in series with the device.
During a short circuit or excess current, the wire melts and opens the circuit, preventing damage to equipment.
A conducting wire allows normal current flow through the circuit.
A low melting point ensures the wire melts before the current becomes dangerously high.
If the wire had a high melting point, it would not melt in time and the equipment could be damaged.
Answer:Option A: conducting and of low melting point
