58) Shunts and multipliers used in moving coil instruments are made up of manganin. The reason for using the above material is that it has :

Positive temperature coefficient of resistance

Negative temperature coefficient of resistance

Perfectly constant temperature coefficient of resistance

Very low (practically constant) temperature coefficient of resistance

Answer is:

Very low (practically constant) temperature coefficient of resistance
