Which of the following is a best resistor?

Solution
The correct option is D manganin
Answer is D.
Manganin wires are used as they have nearly zero temperature coefficient of resistance. This type of resistors has two major advantages.
1) As the wire materials have zero temperature coefficient of resistance, the resistors are very low sensitive to the changing temperature.
2) The resistance value of this type of resistors can be accurately adjusted by controlling the length of wire during wounding.
